Dublin v Mayo AI Final 2017

September 19, 2017

Unfortunately I won’t be in a position to do a half decent write up until much later in the week so below are the usual battery of stats/tables. I will do up a write up at some stage and post it here – mainly for reference when these teams meet in 2018!!!

Listening and reading to some of the coverage post the final what jumps out to me is

O’Connor’s free at the end was outside his range – see the preview. It is so harsh on O’Connor that he takes a hit for stepping up to cover his team’s deficiencies and in some way lessens what he does elsewhere – see his brilliant long range point to draw the game level at the end.

Take a look at the assists table for players who had hugely impactful, under the radar, game

Mayo’s shooting was not poor! It was better than both 2016 AI Finals … it was just that Dublin’s shooting was exceptional. At one stage in the second half they were 0 – 11 from 12 for a Conversion Rate of 92%. Collective ice in their veins.

Dublin v Mayo 2017 All ireland preview

September 14, 2017

Immediate post-game reactions and numbers from the 2016 final can be found here (drawn game) and here (replay). Both will be referenced heavily below

Dublin Attack

We’ll get into the constituent parts below but as a collective Dublin have returned a whopping 61% Conversion Rate so far in 2017. The 188 shots they have attempted has netted them 19 points more (Expt Pts +19.05) than the average intercounty team would have scored. This Dublin attack is rolling.

Point attempts from play

Table 1 in the Appendix shows the breakdown per player but as a collective over two thirds (+13.87) of Dublin’s positive Expt Pts has come from their point attempts from play. The average Conversion Rate over the past 5 years has been 46%; thus far Dublin have returned 56%. The question is not how good they are – we know they are exceptional – but whether they can maintain that level of production?

And it is an open question as we have seen this before. Coming into both the 2015 and 2016 finals Dublin’s forwards were also flying with pre final Conversion Rates of 57% in 2015 (Expt Pts +17.63) and 51% in 2016 (Expt Pts +8.25). In the 2015 final they were impressive in maintaining their high returns with a 57% Conversion Rate (0 – 08 from 14) and a one game Expt Pts of +1.57 (in poor weather it must be remembered). However in the two games against Mayo last year they stumbled to a very poor 37% (0 – 14 from 38; Expt Pts -4.72).

The question is whether this stumble was induced by facing Mayo or was it more of a Dublin blip? There is no way to categorically state either way but looking from the outside I would give Mayo a great deal of credit. Coming into the 2016 final Mayo, in their six games, had allowed a Conversion Rate of 41% (0 – 45 from 109) as opposed to the 51% Dublin had been putting up. Across the two games the 37% Dublin achieved was much more in line with what Mayo had been allowing.

We have a similar scenario this year. Dublin are flying with the aforementioned Conversion Rate of 56% but again over a nine game span Mayo’s defence have only allowed a Conversion Rate of 41% (which, as an aside, shows remarkable consistency year to year). Can Mayo repeat their 2016 trick and “drag” Dublin’s Conversion Rate down in the final?

In an effort to explain the drop in Dublin’s shooting I created a pressure index (see Note1) and noted that Mayo were consistent across the two games in applying strong or severe pressure to just under half of Dublin’s point attempts (45% in the drawn game and 44% in the replay). In 2017 – across the nine games – Mayo have applied strong or severe pressure to 46% of their opponents point attempts. This has risen to 59% in the last four games.

So we know that Dublin can shoot and that they can carry it over (2015 final) however we also know that Mayo stymied them in both games last year and that the pressure index for their 2017 season is trending upwards.

One difference, for Dublin, observed when comparing this year to the last two All Irelands is just who is taking the shots. Below are the top 5 point takers coming into the last three finals and whilst there was a change from ’15 to ’16 the new entrants then were generally known quantities in McManamon & Rock. With Connolly suspended and Brogan & McManamon mainly coming off the bench there is a newer, fresher, look to the Dublin strike force.

Mannion & Andrews are well known to the Mayo defenders at this stage but O’Callaghan – despite there being a mountain of video evidence on him – is new and may cause the Mayo defenders to sit off initially; remember it was the relatively unknown Costelloe off the bench that did the damage in last year’s replay.

Deadballs

Given their experience, both last year and in their run to the final this year, Mayo may believe that they can handle the Dublin forwards. But what they will have to be very conscious of is fouling. Rock had a poor day in last year’s drawn game (0 – 03 from 7 (43%); Expt Pts of -1.58) but was then devastating in the replay (0 – 07 from 7 with an Expt Pts of +1.58).

He, and Dublin as a whole, have maintained this form throughout the 2017 Championship returning a barely credible 94% Conversion Rate (0 – 33 from 35) with an Expt Pts of +6.43 (see Chart 1 in the Appendix).
A special note of praise for Rock here. Although he had an off day in the 2016 drawn final he has been phenomenal since basically being removed from free taking duties at the back end of 2015. In 11 Championship games since the start of 2016 he is 92% and as the below graphic shows he is not only consistent “inside” where he is 96% but also outside (75%). Not only has he accuracy but he has accuracy with length.

Mayo cannot hope that the Rock from the drawn 2016 final appears. Instead they must expect that the Rock we have seen from the start of 2016, and in the 2016 replay, shows up. They gave up seven scoreable frees in the replay; in 2017 they have given up an average of 6.6 shots at goal from frees. Unless defending a lead their target has to be to minimise Rock’s opportunities from frees to seven or less.

Goal attempts

Dublin have – surprisingly given their opposition and reputation – only been average on goal attempts. In 2015 they were averaging 6.0 shots at goal per game but had a phenomenal 60% Conversion Rate (18 – 04 from 30). In 2016 this reduced dramatically to 2.2 attempts & a 46% (5 – 00 from 11) Conversion Rate. So far this year it is back up to 5.0 attempts a game but with a basically average Conversion Rate of 36% (9 – 01 from 25). In the 2015 final they manufactured 4 goal attempts but couldn’t convert any whilst in the two 2016 games they only created four distinct attempts at goal – but did manage to score in the most unconventional manner!

It’s all a bit of a rollercoaster. I think it is fair to say that Dublin are a lot less goal hungry than previous incarnations but this year has seen them somewhat pick up their attempts per game.

Mayo attack

Whereas Dublin are on fire Mayo have been hotter and colder, both from game to game and within games, than any other team. They returned a Conversion Rate of 41% against Galway and 71% against Cork; they scored 1 – 09 from just 12 shots in extra time against Derry after producing 0 – 01 from 15 attempts in a 25 minute spell in the second half. Against Cork they scored 0 -14 from their first 15 point attempts from play.

Mayo are the walking embodiment of the fact that you can twist stats to back up any argument

Point attempts from play

Looking at the nine games in the round (see Table 2 in the appendix) however we can say that their point taking has been just above average (50% Conversion Rate; +2.21 Expt Pts). But this is a step up on their 2016 campaign (46% Conversion Rate; +1.62).

There’s a slight anomaly in the above figures in that Mayo’s Conversion Rate has increased but the Expt Pts has remained more or less static. That’s because Mayo have attempted much more shots from central locations this year compared to last year. In a most Un-Mayo like fashion they have made life easier on themselves!

If we run an imaginary line vertically from the outer edges of the D to the 45m line we create a central channel. In 2016 34% of Mayo’s point attempts came from inside this channel. In 2017 this has risen to 51%.

A lot has been made of Mayo’s reliance on Moran and C O’Connor. Between them they have attempted 32% of Mayo’s point attempts returning 34% of their scores however in truth this is not too far removed from Dublin’s spread. Dublin have relied on O’Callaghan & Mannion for 29% of their point attempts and 30% of their scores. Now the argument can be made that Dublin have more alternatives in Connolly, Brogan, Kilkenny, Rock, Andrews et al should you shut the front two down – and that’s fair – but there are only so many shots to go around. And as good a unit as Kerry’s defence couldn’t shut them down. Moran & C O’Connor took 28% of Mayo’s point attempts across the two semi-finals with a combined Conversion Rate of 72% and Expt Pts of +2.89

Another notable point re Mayo’s shooting is that the “back-up”, the next ten players by shot volume (see Table2 in the Appendix), have been as accurate as Moran & C O’Connor with a 53% Conversion Rate (0 – 55 from 104) compared to Moran/C O’Connor’s 54% (0-34 from 63). Have Mayo got two top shooters? Yes. Have they ready-made, volume based replacements if they are shut down? No. Can the workload be spread and the efficiency maintained if they are shut down? Yes.

What of the Dublin defence? Coming into the 2016 final Mayo were running at an about average Conversion Rate of 45% (Expt Pts +0.89). For the two finals their combined numbers were 0 – 14 from 31 (Conversion Rate of 45%; Expt Pts of +0.22). The sample size is small but Dublin’s defence had no real additional effect on Mayo’s efficiency – Mayo carried over their conversion rate. Where they did have an effect however was in limiting the attempts Mayo had. Coming into the 2016 final Mayo had taken 20.7 point attempts per game. In the final this dropped to 15.5.

This year so far Mayo have averaged (again with remarkable consistency) 20.5 point attempts per game. In 2016 Dublin – prior to the final – had allowed the opposition to take 16.6 point attempts per game but this has risen to 18.6 in 2017. So not only has Mayo’s efficiency on the same volume of shots increased but Dublin are allowing more shots and (in 2016 at least) didn’t have an effect on Mayo’s efficiency.

Deadballs

C O’Connor has been rock steady on frees throughout his career converting, when the pressure has been at its most intense, 86% (0-55 from 64 Expt Pts of +4.99) in semi-final and finals alone from 2012 to 2016. His range does appear to have shortened however.

The above chart shows C O’Connor’s 2017 frees in yellow and using the same boundaries as the Rock chart above we can see that O’Connor is as good as ever “inside”. He has recorded very similar numbers to Rock at 95% (0 – 35 from 37) however he has definitely struggled “outside” recording a very poor (relatively speaking) 35%.
The two black dots on the chart are Jason Doherty’s attempts in the semi-final replay versus Kerry whilst the red cross is the free that O’Connor missed at the death in last year’s replay. As discussed at the time you would not have wanted anyone else standing over that free given his performance in the most pressurised of stages previously but it was definitely on the outer edge of his range.

Given his range limitations, his record this year and how comfortable Doherty looked the last day surely there’s a case for handing over the longer range attempts?

Apart from C O’Connor’s range – which does look to have a ready-made alternative should Mayo wish to employ Doherty – another area of concern would be frees from the right. Attempts from this area are sparse in the above chart (C O’Connor handed the ball to Moran for at least one free from this area against Kerry) as you would imagine C O’Connor is only too aware of his limitations. The issue was only exasperated by McLoughlin missing his two frees from inside the 20m on the right against Derry and Sligo.

Everyone knows O’Connor doesn’t want to take frees from wide right whilst the alternative, in McLoughlin, has, being kind, been shaky. Mayo know this is a weakness. We know it. You can be damn well sure that the Dublin defence knows it too.

Goal attempts

Mayo have been slightly below Dublin in their attempts per game at 4.2 however have been ahead of Dublin with a Conversion Rate of 42% (16 – 03 from 38 attempts). In the round that’s 5.6pts per game from both for their goal attempts (Dublin 5.60, Mayo 5.67).

Kickouts

One of the most eagerly anticipated duals will be the kickouts. How successful will Mayo be at getting their, what at times look extremely dicey, short kickouts away? Will they push up on Dublin? Once won how good will each team be at manoeuvring the subsequent possession into a shot and score?

Dublin Kickouts

See appendix for raw numeric tables

To date Dublin have gone short (see Note 2) on 66% (63 from 96) of their kickouts winning them all and managing to produce a shot from 73% which resulted in 3-27. That’s 0.57 points for every kickout won. Which is incredible. The returns for all other kickouts won is 0.45 – which doesn’t account for the kickouts the lost when the ball went past the 45 – whilst Mayo are a net (unlike Dublin they have lost 9 of their own short kickouts which has resulted in the opposition getting 0 – 03) 0.33 points per short kickout.

You have to imagine that Mayo will look to disrupt this wherever they can. To date 50% of the opposition’s kickouts have gone short in Mayo games with the opposition getting 0.31 points per kickout won. Mayo have gotten their hands on 10% (12 out of 120) of the opposition’s kickouts and when they do they go for goal – scoring 2 – 03 off those 12.
In the two finals last year Dublin had a similar split to this year in that 65% of their kickouts went short but Mayo had much more success keeping Dublin to just 0.12 points per short kickout won (0 – 03 off 25). And that’s without referencing the two short ones that Mayo won.

When we compare this to what Dublin have done to date in the 2017 Championship you have to believe that whilst Mayo may not be able to stop Dublin completely, and may not be able to clamp down as rigidly as they did last year, they should at least provide a much more substantial obstacle than Dublin have faced hitherto fore.

Mayo kickouts

Across both 2016 games Mayo lost five (17%) of their 29 short kickouts against Dublin including two at the death of the drawn game that surely had a part to play in Clarke being dropped for the replay. Clarke is now firmly ensconced as Mayo’s No.1 but the short kickout roulette can still occur at any moment as they have lost 9 across six different games.

Mayo have been somewhat fortunate in that none of those 14 lost short kickouts (5 against Dublin and 9 this year) have resulted in a goal – instead 0 – 08 has come from them – but it is only a matter of time. But Mayo will continue to roll that dice, even in the face of the Dublin pressure, as it has served them well overall. Whilst not as spectacular as Dublin’s 0.57 Mayo have returned 0.39 points for every short kickout won this year.

That does rise to 0.43 for their own kickouts that they win past the 45 however they only win 63% of these – for all the anxiety they give their fans on the short ones they are still winning 90%. It’s almost a no brainer. No matter how many palpitations they give you if your returns are the same on the short ones as on the longer ones but you win more of the short ones – well you keep going short. That is until you give away the inevitable calamitous goal … let’s hope for Mayo’s sake their luck holds for one more game.

Table 3 – Dublin 2017 kickout overview

Table 4 – Mayo 2017 kickout overview

Note 1 – Pressure Index explanation; this is a subjective metric where the pressure applied to a shot from play is given a range from 0 to 3. Very generally
• 0 = no pressure applied,
• 1 = very little (e.g. a player running alongside but not tackling)
• 2 = strong (e.g. on the shoulder, catching the shooters eye by flying in to tackle)
• 3 = intense (e.g. a block, delivering a shoulder just as the shot is being taken)

It does come with a warning as it is subjective but seeing as there is only one person applying the metric you would expect that there would be a level of consistency when a large enough volume of shots is reviewed.

Note 2 – Kickout definition
• Short = ball landing inside the 45
• Mid = ball landing between the 45 & 65
• Long – ball landing past the 65

Again some judgement is required for contested balls around the 45/65 but on a large enough dataset any kinks will be lost to the averages

O’Connor & Rock from frees (Rd3 of league)

March 3, 2017

From an analysis and review standpoint I am forever railing against recency bias. This “railing” comes about however because of its pervasiveness. It’s an in-built near automatic response. And of course I fell into the trap myself.

Watching the Mayo – Roscommon game last week Cillian O’Connor missed a central free about 33metres out and I had immediate flashbacks to (a) a number of missed frees in the previous round against Kerry and (b) that missed free in last year’s All Ireland final.

Was this latest missed free a sign of some cliff having been reached? Was one of Mayo’s most consistent weapons beginning to malfunction? Of course not.

oconnor-post-rd3

In the three league games to date O’Connor has hit 79% of his frees. Well above the ~72% Championship average. On Expt Pts his tally is -0.39; he has basically scored what is expected. Now the argument could be made that someone with O’Connor’s reputation should be in positive Expt Pts territory. Fine. However we must always remember that the Expt Pts tally is based off Championship returns. Frees taken in (mainly) pristine weather on (mainly) pristine surfaces. O’Connor is fine. To be slightly off in the middle of the league is acceptable? For comparison Dean Rock is running at 75% conversion rate with an Expt Pts tally of -0.86.

rock-post-rd3

What I did argue however in last year’s All Ireland review is that O’Connor had an arc outside of which he was vulnerable (the missed free in the drawn All Ireland being right on this arc). Given weather, pitch conditions etc. it is fair to expect that arc to contract at this time of year and if we placed this contracted arc over O’Connor’s frees to date then I would suggest that arguement is still relevant. He has taken 6 frees on the edges of this constricted arc and converted 3 – 50% Success Rate. He has also missed his only 45.

So in conclusion – bloody recency bias!! But O’Connor is generally fine and still remains one of the most consistent free takers once within his range.

Dublin v Mayo 2016 All Ireland Final Replay

October 5, 2016

For those new to the blog, or who haven’t been here for a while, please find a refresher on the definitions and how the numbers are compiled here

Team Possessions Attacks Shots Scores Exp Pts
Dublin 49 38 26 1 – 15 17.59
Mayo 48 36 25 1 – 14 15.62

Attack Rates, Shot Rates, Conversion Rates and points per possessions; all the main metrics were incredibly even – as to be expected in a one point game that lasted over 80 minutes – but was there anything in particular that got Dublin over the line?

Dublin shooting

Deadballs

Dublin, and thus Dean Rock, were spectacular on the day from deadballs converting 100% from eight attempts with an Expt Pts of +2.10. Connolly’s penalty was inch perfect but coming in to the year the conversion rate was 83% (24 goals from 29 shots) so the Expt Pts for a penalty is very high at 2.48. He is expected to convert that. The positive Expt Pts is almost entirely Rock’s.

He scored 0 – 07 on seven attempts with an Expt Pts of +1.58. This from the player who returned a Conversion Rate of 43% (0 – 03 from 7 shots & an Expt Pts of -1.58) in the drawn game. He was essentially removed from frees in last year’s final taking just two of the nine Dublin deadballs after converting just 40% (0 – 02 from five) in that year’s semi-final. That was a performance with an exclamation mark.

This, along with the performance against Kerry in this year’s semi-final (0 – 10 from 11 attempts & Expt Pts of +2.48), should banish any notion that he cannot deliver on the big day. More on Cillian O’Connor below but both himself and Rock are now clearly the best free takers in the country.

Goal chances

One of the more remarkable aspects of the final was the fact that Dublin did not manufacture a shot on goal from play. They did have a few breaks through the middle, such as McManamon being stripped by Harrison after the long kickout from Cluxton or Fitzsimons strolling through the centre at the death, but never got to pull the trigger.

This is the first game since 2012 that this has happened and credit is due to the collective Mayo defence. Especially how they learned the lessons from the first day with Fenton not being allowed drift in behind at any stage.

Point attempts

Dublin recorded a 44% Conversion Rate (0 – 08 from 18) and an Expt Pts tally of -1.69 when shooting from play. In and of itself this is poor but set against the returns from the drawn game (30% from 20 shots and an Expt Pts tally of -3.03) and how Mayo handled Tipperary and Tyrone (26% & -3.11 and 27% & -3.36) it was a step up.

In the drawn game it was highlighted how 50% of Dublin’s scores came from shots with no pressure applied whilst Mayo were able to apply intense pressure to 45% of their shots. Dublin only converted 22% (0 – 02 from 9 attempts) of those taken under this pressure.

Mayo managed to apply the same levels of intense pressure here (44%, 8 of 18 attempts) however Dublin’s shooting was better scoring on 50% (0 – 04) as opposed to the 22% in the drawn game. The level of pressure is illustrated b the fact that Mayo blocked three of those eigth but Dublin just squeezed more out.

That’s not to say that all their shooting was good or improved. I graded 8 shots where no pressure was applied with Dublin only scoring 0 – 03. Undoubtedly it is due to small sample size randomness but on the day those shooting under intense pressure performed better than those that had no pressure applied.

Mayo Shooting

Goal attempts

Mayo had one shot at goal and what a shot. A beautiful goal by Keegan.

A lot of ink was spent on the run up to the game on the battle between Connolly & Keegan and the impact/intensity of that battle can be viewed through the two point attempts they combined for. On Keegan’s point attempt in the 25th minute it is Connolly flying in to put him off. For Connolly’s point attempt in the 34th minute it is Keegan flying in to try – unsuccessfully – and put Connolly off.

keegan-goal-v-dublin

I bring the point attempts up above as when Keegan takes the shot at goal Connolly is not in the picture. When S O’Shea launches the ball into A O’Shea on the 45 Connolly (11) has Keegan (5) within arm’s length but doesn’t track him. By the time Keegan pulls the trigger it is Fitzsimons (22) who has put in an incredible shift from trying to block O’Shea’s kick pass to get back on Keegan’s heel.

Point attempts

Mayo converted 38% of their point attempts (0 – 05 from 13 shots) with an Expt Pts of -0.85.

Dublin managed to properly pressurise five of those 13 shots (38% – similar to Mayo’s 44% on Dublin’s shooting) which was a big step up from the Dublin defence. The last day they only managed to pressurise two, or 11%, of Mayo’s point attempts.

Mayo responded well to this pressure scoring 0 – 03 from the five shots taken under pressure. The problem came when they were placed under no, or minimal, pressure. Here they only scored 0 – 02 from 8 attempts (25% – in the draw game it was 0 – 09 from 16 attempts – 56%).As an illustration C O’Shea & Jason Doherty dropped shots into the goalkeeper’s hands from very central positions when under no pressure whilst Andy Moran pulled one wide from the left inside the 20m line.

They created the chances – the execution just wasn’t there.

Deadballs

Up until the final free kick Cillian O’Connor had been flawless converting 100% of his frees (0 – 09 from 9 attempts) with an Expt Pts of +1.34. This followed on from converting 100% of his frees (0 – 05 frees from 5 attempts) in the drawn game.

And then we had that final free. The average, from 2012 -2015, for the area of the pitch that the free was attempted from (sector6) was 64% on 650 attempts. For the same period I have O’Connor converting 75% from this sector (0 – 09 from 12 attempts). Unsurprisingly, given his overall returns, O’Connor has been – historically – above average from this range.

coc-deadballs-2016

His shot charts for frees in 2016 is above. Overall he was 77% with an Expt Pts of +1.28 and 67% in Sector 6. Below his historical averages but nothing untoward.

What is apparent from the above however is that there is an arc – in the same shape as the D but starting inside the two “x”s at the 20m line above – outside of which is accuracy becomes human! Every free taker has this arc. Basically his range. But in this instance the final free (marked in the above with a black “x”) is right on the O’Connor’s 2016 arc. He had two frees from a similar range against Galway and Westmeath converting one and missing the other.

Anyone who has read this blog for any length of time knows the esteem I hold O’Connor’s deadball ability in. He is the best around (though Rock has now joined him). There is no one else I would want taking that free but it was no “gimme”. It was right on the edge of his 2016 comfort zone.

Kickouts

Mayo won 14 of their 20 kickouts. Of those six were taken by Clarke with Mayo gaining possession on all six whist the split was 8 – 6 in Mayo’s favour when Hennelly was in goal. On its own that looks very poor for Hennelly however of Clarke’s six kickouts we only saw where five landed and of those four (80%) went short. Dublin did not pressurise the recipient on any of these four. Clarke’s kickouts were very safe.

Of Hennelly’s 14 kickouts only six, or 43% ,went short. Hennelly, whether by choice, by design or due to the Dublin press went longer than Clarke and as such placed more in harm’s way. The flip side of this is that Mayo had a net score of four points on Hennelly’s 14 kickouts (scored 1-03 and let in 0-02 directly from the possession’s gained) whereas the net benefit of winning Clarke’s six short kickouts was 0 – 01

A lot has been written about the decision to start Hennelly, and the success of kickouts is as much to do with the outfield players as it is the goalkeeper, but Hennelly was, despite the commentary, coming out on top in terms of end product on the kickouts.

Again the commentary was that Cluxton had a superb game from kickouts. He undoubtedly had some absolute peaches in the second half when he pinged two straight to Flynn & McManamon in midfield but is our view of the overall performance coloured by these just after the Mayo keeper switch?

Mayo lost six out of 20, Dublin lost five out of 21. Better but by no means outstandingly so. By the time Hennelly had lost six Cluxton had lost four. Mayo had a net gain of four points. Dublin? Broke even. Scored 0-02 from the possessions they gained on their own kickout but also conceded 0 – 02 fro he five they lost.

Again a goalkeeper’s role is not all about kickouts. Nor is the goalkeeper the sole reason for a kickout ending to a score. I may be trying to push too positive a spin on Hennelly’s performance (forget trying – I am pushing!) *but* the very negative narrative – in comparison to the very positive one on Cluxton’s – around Hennelly’s kickouts just doesn’t ring entirely true.

How anyone can categorically state that this Mayo team is “gone”, or “cannot win” the big one is beyond me. There was the width of a cigarette paper between these teams. And Dublin are considered one of the greats.

Dublin v Mayo 2016 All Ireland Final

September 20, 2016

For those new to the blog, or who haven’t been here for a while, please find a refresher on the definitions and how the numbers are compiled here

Team Possessions Attacks Shots Scores Exp Pts
Dublin 57 46 31 2 – 09 17.30
Mayo 53 40 26 0 – 15 14.80

Dublin’s returns don’t look too bad – scoring 2 – 09 from an Expected return of 17.30. Those two goals however came from non shots (yes they created the chances but from an Expt Pts vantage they don’t count as they didn’t come from a Dublin shot on goal) meaning that Dublin’s actual shots returned more than 8 points below Expected and showed a Conversion Rate of 29%.

In their five games this year Dublin were showing a 61% Conversion Rate and a combined Expt Pts value of +11.21. In the 23 other Championship games since 2013 Dublin’s Conversion Rate has only dropped below 40% once – and that was a 39% against the ultra-defensive Westmeath in the 2015 Leinster final. The next lowest after that is 44%.

This was a spectacular derailing of the well-oiled machine. How did it happen?

Dublin’s shooting

Goal attempts

Dublin had three goal attempts in two different sequences (Brogan’s shot after Fenton’s original chance was saved as well as Fenton’s second attempt) which produced one goal – but the goal did not come from any of the three Dublin shots. As such the Expt Pts on the three shots was -3.42 (even though Dublin did get 3 points from the scramble – God the Expt Pts model really doesn’t like own goals!).

Note that for the second goal there was no actual goal shot – Rock spilled Connolly’s (wondrous) pass before Boyle put his foot through it.

Just on those two Fenton goal attempts – they were eerily similar with four different Mayo players committing the same basic “lack of communication” mistake.

dub-goal-chance-v-mayo-16-ai-final-actual-1st

In the first Mayo are basically set with S O’Shea (8) on Fenton (8). Fenton lays the ball off to the wrap around player and drifts towards goal however both O’Shea and Higgins (4) then go towards the player with the ball. Neither goes with Fenton.

dub-goal-chance1-v-mayo-16-ai-final

Same again for the second. This time replace McLoughlin (10) for O’Shea and Durcan (7) for Higgins. Fenton lays the ball off to the wraparound runner and continues to drift towards goal. Both Mayo players get sucked to the ball leaving Fenton acres of room in behind.

Deadballs

Unfortunately there is just no hiding from the fact that Rock had a bad day. He scored 0 – 03 from seven attempts for an Expt Pts tally of -1.57.

Much had been made of his 93% success rate this year coming in to the game (0-37 from 40 shots with an Expt pts of +7.98 from frees and 45s) however it must be remembered that he was also on 93% coming in to the 2015 semi-finals. From there on he only converted 0 – 02 from 5 attempts in the two 2015 games against Mayo and only attempted two of Dublin’s nine deadballs in the final against Kerry.

He is undoubtedly the real deal however there have to be concerns about his ability to maintain the averages at the end of the season. His excellent performance against Kerry had put some of these concerns to bed (0 -10 from 11 on frees & 45s with an Expt Pts tally of +2.48) but he’ll have to step up in the replay to silence them again

Then we have Connolly’s sideline attempt. Up until the start of this year’s Championship 18 point attempts from a sideline had been charted with a combined 28% Success Rate. Connolly is a better player than the majority, if not all, of those players who had taken those 18 attempts however (a) he is not the free taker and (b) those 18 were probably taken in better conditions and not in the 74th minute of a pulsating All Ireland final. It was a punt but he was always more likely to give the ball to Mayo having missed than having scored.

Point attempts

That leaves 20 point attempts throughout the game which saw Dublin convert 30% (0 – 06) with an Expt Pts tally of -3.03. Granted the conditions were not great but that is just very, very poor. And it was not confined to a handful of individuals having a day off – 12 separate Dublin players had a point attempt. There was just no sign of this.

In reviewing the SF against Tipperary we noted that the Mayo defence had restricted Tyrone to 27% and an Expt Pt return of -3.36 whilst holding the previously free scoring Tipperary to 26% and -3.11. We now add Dublin’s 30% and -3.03 to that tally. They are obviously doing something right. Against Tipperary & Tyrone they applied pressure to 66% of their point attempts when the norm is somewhere around the 51% mark. Again here they pressurised – to one extent or another – 75% of Dublin’s shots. But that doesn’t fully tell the story. In an attempt to somewhat measure what they were doing I graded all pressure on the shooter from 0 (no pressure applied) to 3 (intense pressure)

pressure-index

As can be seen Mayo were very good at applying intense pressure to 45% of Dublin’s point attempts. We don’t have any other comparison point for this but Dublin only applied a similar amount of pressure to 11% of Mayo’s shots.

It is no fluke that Dublin struggled – but it is strange that they struggled so much.

Note Colm Boyle shows up really well in this context. I have him charted as applying pressure to four separate shots with three of the being strong pressure (one “2” in the above table and two “3”s)

Mayo shooting

Goal attempts

Mayo had two clear cut goal attempts coming away with 0-01. The first fell very early to Durcan who had his shot blocked by Cooper. Hindsight is 20:20 and all that but looking at the position just as he was about to strike you would love to have seen him ship it left where they had an overlap with two of their best finishers standing on the square
mayo-goal-chance1-v-dub-16-ai-final
The second one was Moran’s attempt on the 52nd minute
mayo-goal-chance2-v-dub-16-ai-final
There was a split second where O’Connor was free on the square and when I put the still up on Twitter there was a split opinion on whether the ball needed to be fisted across. Personally the picture makes a fisted pass look a lot easier than real time did – it would have to have been spot on – and I would want Moran having the confidence to take that shot on.

Point attempts

Mayo were slightly above average with a Conversion Rate of 50% (0-09 from 18 shots) and an Expt Pts of +1.07.
Much like Dublin there was a large spread of shooters with ten different players having a shot. O’Connor & Vaughan showed well here scoring 0 – 02 from three attempts each but the overall spread means that no one really stood out.

Again like Dublin however there were some wild efforts in there – not sure either O’Shea should be taking pot shots outside the 45!

Deadballs

Immediately after the game concluded the thought had been that O’Connor’s deadball day had been spectacular. That however was more in comparison to Rock than anything else. O’Connor converted 86% (0 – 05 from 6 shots) with an Expt Pts was +0.41. A good day’s return on the numbers; nothing more.

However when looking at that stat line we need to take into account the context of the game. If Rock has question marks about him on the big day then O’Connor is the exact opposite – he thrives on it.

In eight All Ireland finals and semi-finals since 2013 O’Connor is 81% on frees and 45s (0 – 09 from 48 attempts) with an Expt Pts tally of +2.44. When everything is to play for O’Connor delivers well above average.

Kickouts

Dublin won 18 of their 22 but only managed 0-01, or 0.06 points per kickout won, from those 18 wins. In the 2016 Championship to date that was 0.51 points per kickout won. Another one to chalk down for the Mayo defence.

Another minor victory can be noted in the time it took Cluxton to get his kicks off. A lot had been made in the build up to the match as to how Cluxton looked to get his kickouts taken within six seconds. We didn’t see a number of the kickouts but when we did Cluxton was regularly taking over 15 seconds to kick the ball out (the first few were indicative; – stalled as had to be retaken, 15 second wait, 16 seconds, didn’t see on TV coverage, 12 seconds, 14 seconds, delayed for the black card, 20 seconds).

Mayo were, score wise, better racking up 0 – 04 on the 16 kickouts they won – 0.25 points per kickout – however they also coughed up 0 – 02 and nearly had a calamitous last few minutes when Clarke hit three poor kickouts in quick succession. The first was lofted to Parsons on the 45m line on the right wing allowing Mannion to break the ball to O’Gara forcing Barrett to give away a free that Rock pointed. On the resultant kickout Clarke managed to pick out Connolly short left who took one look and pointed. Clarke then placed Higgins under all sorts of trouble when he went short right.

Up until those three kickouts Mayo had taken 17 winning 14 – however when they went past the 45 they had lost three out of four. Given this, and the sequence above, it will be interesting to see if Dublin push up the next day putting Clarke under pressure and forcing him to go longer.

Dublin v Kerry 2016 AI Semi Final

August 30, 2016

For those new to the blog, or who haven’t been here for a while, please find a refresher on the definitions and how the numbers are compiled here

Team Possessions Attacks Shots Scores Exp Pts
Dublin 56 42 35 0 – 22 19.14
Kerry 51 35 26 2 – 14 16.48

Normally we look at the game as a whole however this one ebbed and flowed to such an extent that it may be better to review how both teams did within the various segments that made up the game.

Kerry’s slow start
Colm Cooper and Donnchadh Walsh both missed close in chances early on – Cooper pulling an attempt on the spin whilst Walsh was off balance after a thunderous shoulder from Byrne – which put them in a hole both in terms of the match and their shooting returns (as both were from the zone immediately in front of goal Kerry’s Expt Pts were -1.50 by the 3rd minute!).

They then went ten minutes without another shot by which time Dublin had scored 0 – 04 from eight point attempts (shooting was average here with an Expt Pts of +0.26) whilst McMahon also missed Dublin’s only goal chance.

As an aside Kerry are only the second team since the start of the 2012 Championship to restrict Dublin to just one shot at goal in a game. The other, somewhat surprisingly, was Meath in this year’s Leinster Championship.

We then had a period of sublime accuracy as both teams combined for 0 – 11 from just 14 shots over a 16 minute spell (79% combined with an Expt Pts of +2.84). Kerry were the main contributors here scoring 0 – 06 from just the six shots (Expt Pts of +1.99) with Geaney hitting three from play. Dublin thus scored 0 – 05 from 8 shots and whilst they did not quite attain Kerry’s level of accuracy it was still above expected (Expt Pts +0.85).

So up until the goal Dublin were well on top in the shot count – 17 to Kerry’s 8 – but Kerry’s accuracy was keeping them within reach.

But it wasn’t just in terms of shots that Dublin were ahead. They had 28 possessions & 20 attacks (71% Attack Rate) to Kerry’s 20 possessions and just 9 attacks (45% Attack Rate). Kerry were being consumed. The extra possessions came from Dublin’s success on Kerry’s kickouts. Dublin had six kickouts prior to the first goal winning all six. Kerry had 14 kickouts but only managed to win seven with three of those going short. So when the Kerry kickout became contestable Dublin were 7 – 4 ahead. Dublin winning the opposition’s kickouts is not that much of a surprise any more however Kerry refused to help themselves here. There was no variation – all 11 were directed at either Moran or Maher and all went mid-range between the 20 and 45metre lines. Fenton, MacAuley & Kilkenny in particular had a field day.

And what of Kerry’s anaemic attack? Yes their forwards were (extremely) economic scoring 0-06 from nine attacks (Dublin were 0-09 from 20) but to only manufacture nine attacks? A lot of this can be attributed to the plan Kerry employed early with long balls being sent in to Colm Cooper & Donaghy. They were getting some success but not enough were sticking and Johnny Cooper can take a lot of the credit for this. He was immense in this period breaking five such balls away from both (two from Donaghy & three from Colm Cooper).

And then the goal
Of Dublin’s first six kickouts three went to the right and short with no pressure applied. Then the 7th went horribly awry. All of a sudden the tables turned. After only conjuring up nine attacks in 29 minutes Kerry manufactured seven in the last 8 minutes with six shots producing 2-02 (Expt Pts of +3.44). Dublin couldn’t get out of their own way losing four of their five kickouts in this period and only managing two possessions in ~8 minutes (one was lost inside Kerry’s 45 when McManamon was tackled and another when Kilkenny fisted the ball away in Kerry’s 65)

Dubs don’t panic
As the numbers from above show Dublin were absolutely rattled going in at half time. They had dominated the game for 30 minutes but had come undone under a deluge of Kerry counter punches.

What happened next says a lot about where this Dublin team are at. They came out in the second half and didn’t panic. They just continued on in the same vein that allowed them to dominate the first 30 minutes. Within 14 minutes of the restart they were back level.

Again the “volume” pressure began to tell. In those opening 14 minutes the shot count was 8 – 3 in Dublin’s favour. This time it was Dublin who were deadly accurate scoring 0 – 06 from those eight shots (Expt Pts +1.47). Dean Rock had a great game (0 -12 from 13 shots including two 45s and two from play) but he was particularly good in this period scoring 0 – 04 (including a 45 & one from play) as well as providing an assist for Fenton’s equaliser.

Kerry’s earlier efficiency failed them here with the only point they scored coming from a Cooper free whilst he also dropped one short off his left into Cluxton’s hands.

One thing that did change here was the possession pattern. For those opening 14 minutes Kerry were “only” 11-9 down in terms of possessions. The reason being that they started to change their kickouts to shorter ones. In that opening period Kerry had seven kickouts with four going short (Dublin did still win the “contestable ones 2-1). Dublin only had the two kickouts in this period winning both – interestingly neither went short!

Kerry mini revival
To all intents & purposes Kerry looked done. They had now played the guts of 50 minutes and had been comprehensively outplayed for 40. To their eternal credit they were far from done however.

Around the time of Fenton’s equaliser Kerry introduced BJ Keane, James O’Donoghue and Brian O’Beaglaoich within five minutes of each other. The freshness – or just their innate obdurateness – saw them wrestle control back manufacturing 0 – 03 from five shots in ten minutes whilst Dublin went into their shell somewhat managing just two wides (an ill-advised long range attempt from Byrne and Rock’s only miss of the game) from a relatively paltry five possessions.

Initially there were 20 possessions in the opening 14 minutes of the half but this slowed to 11 in the next 11 minutes. The game slowed right down and it suited Kerry.

The finale
And then we had the last 15 minutes within which Dublin were frankly superb. They had nine possessions in this period, excluding the final one after Kilkenny got thrown to the ground, progressing all nine inside Kerry’s 45 and getting eight shots off scoring 0 – 07. Under the most intense pressure, starting the period three points down, they produced an 89% Shot Rate and an 88% Conversion Rate with an Expt Pts of +2.17. Just outstanding.

Kerry had their opportunities. They too had nine possessions in this period progressing seven inside Dublin’s 45 however they only produced four shots (57% Conversion Rate) with only one of those coming inside the final ~12 minutes.

We will probably never know what led to such a diversion in those final 15 minutes – be it mental fortitude or the age profile of the teams finally catching up on Kerry – but what we can say is that this Dublin team answered every question about their resolve, ability and just fundamental skills in that final period.

Dublin v Donegal 2016 AI Quarter Final

August 11, 2016

For those new to the blog, or who haven’t been here for a while, please find a refresher on the definitions and how the numbers are compiled here

Team Possessions Attacks Shots Scores Exp Pts
Dublin 41 35 27 1 – 15 18.71
Donegal 42 28 24 1 – 10 11.99

Mannion’s late late goal would appear to give the Dublin shooting a boost that their shooting performance until that point did not warrant (they were running at an Expt Pts of -2.35 until the goal). In truth their shooting was average throughout with the two early missed Connolly goal chances putting them in a hole that only that late goal really bridged.

Dublin shooting

Rock was excellent on deadballs hitting five from five though his Expt Pts return for that is relatively low at +0.93. This is due, as can be seen from the shot chart below, to the fact that three of his frees were from the 14m line in front of goal. These are converted ~98% of the time.

From play their point taking was just below average with an Expt Pts of -0.56. Their conversion rate at 50% (0-10 from 20 shots) would not normally produce a negative Expt Pts however it occurs here due to the shot mix. Dublin were 71% (5 from 7; Expt Pts of +0.56) from central areas and 42% (5 from 12; Expt Pts -1.12) from wider out.

Essentially they were very good on the easier ones, bolstering the Conversion Rate, and poor on the harder ones. This poorer return from the more difficult shots was not due to any particularly pressurised Donegal defending. Four of the seven misses did not occur under any pressure.

This doesn’t appear to be something to get too worried about from a Dublin perspective however. In their two games covered to date (against Laois & Meath – the Westmeath game is on the “to do” list) they had a combined Conversion Rate of 53% (19 from 36) with an Expt Pts of +3.18 from these wider areas. The only caveat to those numbers is that Laois & Meath only pressurised ~31% of those kicks whilst Donegal got pressure on 50%.

Donegal shooting

Donegal were very good on deadballs converting 89% with the only miss being Murphy’s long range effort from beyond the 45 in the 3rd minute. Their Expt Pts for these nine shots comes in at +2.41 but this is somewhat bolstered by the last free. Usually a free is tapped over from that distance and a point gains you a miserly +0.02 on Expt Pts (see Rock’s Conversion Rate to Expt Pts return). Here Murphy got the point but went for goal. We have only 10 instances of a player going for goal from this distance and the majority get blocked. The fact that Murphy was going for goal means that the Expt Pts for that shot was a low +0.33. When the ball ricocheted over the crossbar he, and Donegal, gets a somewhat fortuitous +0.67 bump on Expt Pts.

Donegal scored 1-00 from their two goal chances returning +1.28.

So from deadballs and goal attempts Donegal were running at +3.69 which is in the 2014 “creating a shock” range. But then there is their shooting from play which in truth was both poor and meagre. Donegal returned 0 – 02 from 13 shots (Conversion Rate of 15% & an Expt Pts of -2.68). A lower expectancy is already built in to take account of the fact that Donegal were facing the best team in Ireland so the poor returns cannot be blamed on coming up against a good defence alone.

Donegal had six shots centrally from outside the 20m line and only returned 0 – 01. Dublin managed to pressure just one of those six so four of the remaining five were misses from the central region with no pressure. You just cannot do that – with a lower shot count – against a team like Dublin.

It is interesting to note that McBrearty didn’t get any shots from this central zone. After his heroics the last day he was restricted to four shots with all four coming from out wider.

Dublin’s Kickouts.

All this buries the lead. The most remarkable number from the game is 1-11. That is how much Dublin scored from their own kickout. They somehow managed to score 1 – 11 off 17 possessions gained in this manner and 0-04 from the remaining 24 possessions. That is a remarkable split

Against Meath and Laois they scored a combined 1- 15 from 38 possession on their own kickouts. This equates to 0.47 points per kickout won and 38% of their total score in those games. Here those figures were 0.82 points per possession and 78% of the total score. This game’s lop-sidedness does look like an outlier but that doesn’t make it any less impressive.

Dublin gained possession on 17 of their 21 kickouts (81%) with 13 of those possessions ending in a shot. That means in scoring 1 – 11 the conversion rate for shots emanating from their own kickouts was 92% (!!) with the conversion rate for all other shots being 29% (4 from 14).

Of those 13 shots the range of individual player possessions was 1 to 12 with the average being 6.1. So in essence from their own kickouts 6 players touched the ball (including the shooter) before they pulled the trigger. For the other 14 shots the average was 9.1.

Interesting as that gap is (and what it perhaps implies for the disparate conversion rates?) what’s more interesting is the volume of player possessions inside the 45. Again on the 13 shots from their own kickout there were 1.7 player possessions inside Donegal’s 45. On 8 of the 13 the only possession inside the 45 led to a shot. Again for the other 14 shots this was 2.9

So Dublin held on to the ball a lot less from their own kickouts and were devastatingly incisive once inside the 45 on these possessions. On turnovers, or the opposition’s kickout, where they got ball much higher up the pitch they were more controlled, more methodical. And much less accurate.

Dublin v Kerry 2016 League Final

April 26, 2016

Over 70 minutes (or ~75 these days) that’s a paddlin’.

Team Possessions Attacks Shots Scores Exp Pts
Dublin 60 50 33 2 – 18 21.60
Kerry 47 27 19 0 – 13 9.10

With a full complement of players you are liable to mental and physical fatigue having ~10 less possessions going into the last ten minutes. You just cannot afford to go a man down against Dublin given the pace at which they play the game.

I’m not sure there’s any benefit to be had looking at the game as a whole. Dublin ran riot in the last ten minutes attempting seven shots and scoring 2-03. But the demarcation point was probably the red card ten minutes earlier in the 50th minute. At that stage the score was 0-13 to 0-11 and whilst Dublin were on top it was still competitive. To that end below are the numbers up until the red card.

Team Possessions Attacks Shots Scores Exp Pts
Dublin 40 32 22 0 – 13 12.17
Kerry 33 22 16 0 – 11 8.11

Dublin had more possessions and were finding it easier to get the ball inside Kerry’s 45 (83% Attack rate to Kerry’s very poor 57%). More possession and a higher attack rate will naturally lead to more shots. One crumb of comfort for Kerry is that once inside the 45 they were producing more shots (73% Shot rate to Dublin’s 69%).

One reason for this higher shot rate is the range that Kerry were shooting from. In the period up to the red card Dublin had 17 point attempts from play and all bar two were within ~30 metres of goal. Dublin were working the ball in close attempting higher percentage shots. Hence why on a 59% (13 scores from 22 shots)Success Rate they were only ~1pt above Expected.

Dublin shooting pre red card
Kerry shooting (V Dublin 16 league final) pre red

Kerry on the other hand were taking much harder shots but were converting them at a very high rate as evidenced by the Success Rate of 69% (11 from 16) and an ExpPts of +2.89. Reviewing the semi-final win over Roscommon I was interested to see whether the fast, accurate start Kerry had produced there, and against Cork, could be repeated. The accuracy was – they only missed two shots from play in the first half with one of them being Marc O’Sé’s attempt in the first minute. The speed however wasn’t. They need to be taking more shots, or get a goal, to keep up with Dublin.

Re goal attempts; Darran O’Sullivan’s left footed effort after 22 minutes was the only one Kerry have managed across the last two finals (here & the All Ireland final in September). Dublin had four in the All Ireland final and one up until the red card here. Granted they didn’t convert any but if/when they meet again the goal attempts cannot be 5 -1 in Dublin’s favour. They will eventually convert!

Brogan

Speaking of converting – Bernard Brogan had an ominously good day. Prior to 2015 his returns from play were well below what was required for a forward of his calibre (combined ExptPts of -4.78 over the three years) but with the burden of the free taking duties removed he exploded on the 2015 Championship with an ExpPts return of +14.26 across 38 shots.

Brogan 2015 shot chart
Brogan 2015 shooting

As his shot chart above shows he played much closer to goal in 2015. He did the same here scoring four points from his four shots and setting up both goals. Dublin are not short of options up front but they may not need to exercise them if Brogan maintains his 2015 form.

Kickouts
As ever with Dublin games the kickouts were a focus for a lot of the build-up. Kerry had some success here in the All Ireland final getting their hands on three of Cluxton’s ten short kickouts and the expectation was that they were going to do a similar “press” here. No such luck. Dublin dominated their own kickout winning 89% (16 of 18). More tellingly they managed to score 0-07 directly from those 16 possessions.

When discussing the kickouts pre game a lot of focus is on the Dublin kickout but little emphasis is placed on just how good they are on the opposition’s kickout. Here Kerry went past the 45m line (were forced to go past?) on 19 kickouts winning the possession battle 11-8. Despite this supremacy they only scored 0 – 02 from these possessions whilst Dublin managed to produce 0 – 04 from the 8 kickouts they won.

Dublin dominated their own kickouts with a net return of 0 – 06 (Kerry managed 0 – 01 from the two Dublin kickouts they won) and had a net return of 0 – 02 off Kerry’s contestable kickouts. That’s 0 – 08 to the good on kickouts alone without mentioning the goal.

Kickouts going askew are a natural hazard of using short routines. The idea is that over time you will gain more from the 95% successful short kickouts than you will lose from the 5% that go wrong. That is fine in a macro sense however over 70 minutes one going wrong can be devastating and with the frequency of short kickouts increasing we are seeing more and more erroneous ones being punished to the full. Donegal in the 2014 All Ireland final, Roscommon at the end of their first Division one game against Monaghan and now this. All punished by clinical forwards.

Kealy’s kickout wasn’t the first to go wrong. It won’t be the last.

Dublin v Donegal 2016 League SF

April 12, 2016

There is no point pretending that this game was anything other than a run out. As Chris McNulty commented on Twitter (@chrismcnulty86 – a good follow on all things Donegal) Donegal took the game so seriously that they didn’t train all week. I have completely forgotten who, so apologies for not crediting, but some other wag commented that it was like an exhibition match at the opening of a new ground (see note1). It just had that feel to it.

Still. The two teams may not have engaged as if it were the height of Summer but we we’ll fire up the numbers and see what it throws up.

Team Possessions Attacks Shots Scores Exp Pts
Dublin 52 46 30 1 – 20 18.87
Donegal 46 38 27 0 – 13 16.08

In the opening league game between these two Dublin were restricted to a 76% attack rate and 21 shots. Here it was an 88% attack rate and 30 shots. Again in that opening game Dublin managed (or maybe more accurately the Donegal defense allowed) 0.29 points per possession. Here it was 0.44. There was just no bite to Donegal.

It was not like there was a huge difference in opportunities between the halves either. The goal at the start of the second half did not see Donegal switch off. Both, by some statistical quirk, had stat lines of 26 possessions with 23 attacks and 15 shots. Dublin were slightly more accurate in the first half with a conversion rate of 73% (0-11 from the 15 shots) though the second half conversion rate of 67% (1 – 09 from 15) was also very efficient.

Although they may not take much from the game one positive aspect, from a Dublin perspective, is that their early accuracy came despite the fact that two of their main strife force, Brogan & Mannion, combined for a mere two shots in the first half.

What of Donegal? It may come as some surprise to note that – in pure shooting terms – they were not all that far behind Dublin.

Dub - Don league SF Expt Pts

The above graph shows the team’s respective shooting broken down into actual score vs Expected score (see note2). Donegal, despite what was noted above re application, were on track with Dublin up until the ~33rd minute. Dublin tagged on 0 – 03 at the end of the first half and kicked off with a goal at the start of the 2nd but up until then Donegal were right with them.

The “but” quite obviously comes with caveats. The first being that whilst teams with average returns from the shots attempted would have been level around the 33rd minute Dublin are not average. Nor in their own ways are Mayo or Kerry. Dublin outperformed their Expt Pts from the get go (as an aside Kerry did something vaguely similar against Cork. That day they score 0 – 10 from their first 12 shots inside 20 minutes and were up and gone. It will be interesting to see the starts both teams make, or are allowed make, in the final. But I digress). On top of this Donegal lagged behind what was expected. One of the hallmarks of the 2012 & 2014 teams was their remarkable accuracy in games where the shot counts were very low. They will need to regain this accuracy.

A second point on the Donegal shooting was just how reliant they were on Murphy & McBrearty. Here they accounted for 70% of Donegal’s shots (Dublin’s top 3 marksmen in terms of Volume – Rock, Brogan & Kilkenny accounted for 52% combined). In the opening league game this duo accounted for a more realistic 45% of shots.

Part of this over reliance on Murphy & McBrearty was Donegal’s volume of shots from frees. In total they had 11 shots on goal from free kicks. Dublin had a mere four (plus one 45). Relying on frees as a way to keep the scoreboard ticking over is a tried and trusted manner but in many ways it is dicey proposition as gaining a free is not always within your control. You are reliant on the defender’s, and perhaps more importantly the referee’s, complicity.

Finally Dublin’s Expt Pts was boosted by creating goal chances. They had four shots at goal in total scoring 1 – 01 (about what is expected). Donegal only manufactured the one shot at goal and that a weak, in terms of where the shot was taken from, one from Murphy in the dying embers of the game that went straight at Cluxton. In fairness in the three other Donegal league games that I charted (Roscommon, Kerry & Dublin) they came out even in goal shots in all three so this game may not be emblematic.

So is there hope for Donegal? Absolutely. Over the two games they created as many shots as Dublin. In the first game, when they were not at full tilt but were at least more inclined to try than here, they were able to restrict Dublin’s shooting. But there are also some obvious dangers. They must ensure the shooting volumes are not as concentrated as in this game and also improve their accuracy from play (1-06 from 27 shots over the two Dublin games for a success rate of 26%). The control – in terms of game tempo and shot selection – needs to re-emerge. Goals need to be kept to a minimum. The restrictive game plan does not lend itself to chasing games.

Note1; if you have a twitter account it’s probably better to follow me there (@dontfoul). I tend to have game “scorecards”, like the below, up a lot quicker than the blog posts. Plus by having the game capsule up there I don’t feel the need to get every stat up here!

Note2; I have a piece half written on Expected Points which I will publish prior to the Championship. In essence it is the same measurement as the weighting that has been used heretofore but (hopefully) is a lot more readily understood.
