You say you want a Revolution – A different angle on PWP and Team Performance

A superb run with five wins and a draw in six games; by most standards that is a compelling argument for consistency.  I agree and their overall Composite Possession with Purpose Index rating continues to climb.

They’ve (New England) climbed from 17th in PWP (week 5) to 7th after week 11; a superb shift of 10 full places in 6 weeks.

So in considering this giant push forward I’d like to take a different approach in how the data points from PWP can be viewed.  

This is new so please bear with me for a minute or two as I set the context.

Below are a number of diagrams referencing my PWP indicators for a few teams; the diagram being used this time is the ‘doughnut’ diagram from Microsoft Powerpoint.

The interesting thing about this diagram is that it allows me to offer up a view on my PWP data points that isn’t relative to the exponential relationship (a line). Instead, it allows me to picture the overall tenor of PWP data points in relationship to themselves as being a part of a ‘whole’; with the ‘whole’ being PWP.

I feel confident I can take this approach since my Expected Wins 2 correlation for my data points is ~.97 (R2) — as near to rock solid as you can get.

Other context points include:  

  • The teams used in this analysis are Seattle, New England, Montreal, Portland and last years’ Supporters Shield winner (New York) plus last years bottom dweller (DC United)
  • Reminder in case my explanation was a bit wordy above – the percentages indicated in the doughnut are not the percentages of those activities relative to the game; they are the percentage of those activities relative to each other with 100% being all those activities added together.
  • Source – as usual the MLS Chalkboard and the MLS Statistics Sheets
  • Gold Stars on the diagrams are intended to show you where differences occur.
  • The team name on the outside of the doughnut is the outer ring of data and the team name on the inside of the doughnut is the inner ring of data.

To begin…

The volume of Final Third passes successfully completed by New England (29%) is 3% points higher than Montreal (26%).  Note also that Montreal has a greater percentage of PWP outside the Final Third (30%) than New England (28%). Both of these indicate to me that New England is more focused on penetrating and creating than Montreal.

For the future I will check into these three areas when looking to see if a ‘direct attacking approach’ can be better differentiated from a ‘ground-based’ (short passing scheme) approach.

The actual volume of penetration is higher for New England as well (11%) versus (7%). And like my regular PWP analysis the data here also supports the fact that teams who are more patient in creating shots taken (6% for NER versus 11% for MIFC) end up with more goals scored.

I did ask Matthias Kullowatz about the specific shot data for New England and Montreal; ~60% of Montreal’s shots on target have come outside the prime scoring zones 1 & 2 while ~68% of the Revolution shots on target have also come outside of zones 1 & 2.  So what’s different?

I think it’s down to time and space again; though it could be the Revolution have better strikers – but when you see the DC United doughnut diagram a bit later I think it’s back to time and space; and with fewer shots taken and more patience in the final third that seems reasonable to me.

Now for a contrast that might be better at explaining individual mistakes and bad fortune more than a bad ‘style/system’…

Notice no ‘gold stars’; why? Because there really isn’t that much difference between how these two teams execute the six steps of PWP.

What separates these two teams in the league table are individual mental mistakes in defense – Portland sit on ten points while Seattle have 25. Through the course of this year the Timbers have dropped 7 points due to red cards and penalties – they did both against Columbus Saturday night!

In considering the ‘sameness’ of the data I expect as time passes an output similar to this could highlight ‘individual mistakes’ and perhaps ‘good/bad luck’ when it comes to rebounds and deflections – again recall Saturday night when Futty Danso deflected a shot and notched an ‘own-goal’

All told things went pretty well for Columbus, a red card by their opponent, a foul in the penalty box by their opponent for a PK and a deflected own-goal by their opponent. If I were a Columbus fan I’d be pretty pissed they didn’t win – bad luck for the Crew!

However viewed I’ll revisit this diagram later when the Cascadia Cup battle heats up.

So here’s the doughnut view of New York compared to DC United last year and then a bit further down how they look compared to each other this year.

PWP Doughnut Diagram NYRB v DCU 2013

PWP Doughnut Diagram NYRB v DCU 2013

First off – let’s not forget Ben Olsen was not fired and perhaps this doughnut diagram can also help explain why given the overall poor performance in results last year for DC United.

Notice that the team does exceedingly well in comparison to New York with respect to Passing, penetration and creation; they actually exceed New York in the first two categories and only fall off when it comes to goals scored (7% for DC United versus 15% for New York).

So I’d offer that the system Ben Olsen ran last year worked – what he lacked was a pair of good strikers.  And if you recall the Montreal doughnut earlier the outputs from DC United do not mirror those of the Impact!

They added Espindola and Johnson and shored up their defense a bit; that also included adding Amos Magee to the staff.  Remember him as the Defensive Coordinator for Portland last year (I think – others can confirm or deny that I’m sure)

Bottom line here – the system didn’t change and the Head Coach didn’t change and I’d offer that was appropriate…  now for the same diagram this year:

In closing:

Note the increase for DC United in the final category – goals scored versus shots on goal – pretty compelling information to reinforce that the system used last year is the same system used this year and the difference – major difference – is the addition of two quality strikers.

I’m just in the learning stages on how this new doughnut diagram will take shape – I’m pretty sure it will have at least one hole in it – I’m hopeful there aren’t a lot more.

Some changes afoot with OPTA and MLS – I see OPTA incorporated the Final Third Passing Accuracy suggestion – just need to find out if crosses are included in that metric???

As for the new MLS Chalkboard – I’m not sure how that will work if the ‘numbers’ of activities are not available to count when it comes to defensive activities and ‘touches’ for players…

And yes, the old Chalkboard still appears to exist given a separate link within previous articles but it’s unclear if this change will be a permanent change for next year – or even the World Cup for that matter…

As for This Week in PWP; if you saw my tweets yesterday you know the top Attacking and Defending PWP teams of the week; New England in attack and Toronto in Defense with the Reds taking the Composite PWP Index top spot for Week 11.  

Sporting KC, along with LA Galaxy remain atop the Composite PWP through Week 11 while the Revolution moved to 7th and Columbus dropped to 4th as Real Salt Lake are now in a comfortable position of 3rd best overall.

Finally, this view also gives you and idea of what percentage each team gleans from each of the PWP Six Steps data points in the calculation for the overall Index number.

Headline match-up in Week 13 – Real Salt Lake v Seattle Sounders

Pedigree and consistency of purpose are two words/phrases that come to mind when I consider these teams.  Both are currently doing very well and in my Composite PWP Index, after 12 weeks, they sit in positions four and five.

In considering this early-to-mid-season marquee match-up I’ve put together a few diagrams that might help paint a picture on how effective these two teams are.

My approach will consider how well Real Salt Lake has performed on the road this year versus how well Seattle have performed at home this year; I hope you enjoy it.

But before starting the Capt. Obvious — both teams have some players missing.  With this being Week 13 RSL have used 15 different field players this year while Seattle have used 18.

So although key-players are missing I don’t really think it matters that much – what matters for me, is the beginning words; pedigree and consistency of purpose through the course of this season so far.

And given RSL are unbeaten while Seattle have 26 points with 13 games played the ‘key-player-missing-theme’ just doesn’t work for me.

Given that here’s my latest Doughnut Diagrams for Real Salt Lake versus Seattle; first one up is showing the weighted averages on how each team has attacked their opponent this year (RSL in away games) and (SSFC in home games).

Takeaways…

Not much separates the two teams when looking at what percentage each of the activities in PWP amounts to in relationship to each other – the only one showing any real difference is the amount of Shots on Goal versus Shots Taken for Real Salt Lake.

Given the same rough volume of Shots Taken per penetration (7%) for both teams, RSL are more effective in converting those Shots Taken to Shots on Goal.

In viewing the next percentage – converting those Shots on Goal to Goals Scored there is a slight edge to Seattle.

In total though, both teams are +5 in their Goal Differential (RSL on the road) and (SSFC at home).

Early indications are this should be a very tight game.

The next diagram offers up how each team performs in defense against their opponents attack:

Takeaways…

While some may disagree with this view I would submit this diagram helps speak to how these two teams defend differently yet they end up with the same result.

Note that RSL opponents have yielded less volume in their opponent passing accuracy within and outside the final third but greater volume in penetrating and creating shots.

For me that indicates RSL have a tendency to apply pressure higher up the pitch.

On the other hand the Seattle opponent percentages seem to indicate to me that their defense tucks in a bit more in the final third with the intent of giving their opponent a wee bit more possession outside the final third.

However viewed both teams appear matched evenly when it comes to preventing Shots on Goal and Goals Scored.

An interesting thing to watch for in this game might be how high up the pitch Alonso ventures versus Grossman (the likely replacement for Beckerman).

I would offer the more Alonso commits himself outside the final third the more likely RSL are to score.

On to the standard team performance percentages from the six steps in Possession with Purpose:

Below is the diagram showing the percentages of RSL and how they defend on the road, versus SSFC and how they attack at home.

PWP RSL attacking v SSFC defending

PWP RSL attacking v SSFC defending

Takeaways…

I’ve highlighted two areas; the Shots on Goal versus Shots Taken and the Goals Scored versus Shots on Goal; note that when Seattle attacks 40% of their Shots Taken end up on Goal with roughly 28% of those hitting the back of the net.

Conversely, when RSL defends on the road they are pretty stingy when it comes to yielding Shots on Goal; ~30%, but when the opponent does put that Shot on Goal about ~37% of those shots hit the back of the net.

All told the other indicators seem to support a high level of passing accuracy and possession; if the opponent (dark blue bar for SSFC is 46% then SSFC averages 54% at home in attack.

Next up the view on how RSL attacks on the road versus how SSFC defends at home.

PWP RSL defending v SSFC attacking

PWP RSL defending v SSFC attacking

Takeaways…

Again the highlighted area for RSL is Shots on Goal versus Shots Taken – clearly (given the lower amount of Shots Taken per penetration) (light blue bar – ~18%) RSL takes its time in setting up shots that are more likely to be on target – and scoring is not a problem given their +5 goal differential on the road.

As for Seattle, they yield, on average, about the same amount of Shots Taken per penetration but the resultant indicates they are more successful in preventing that Shot Taken from becoming a Shot on Goal < ~30%.

Another indicator reinforcing that they appear to work towards closing down their opponents more tightly within their defending third.

In closing…

I’m not sure we see a tight game here – it’s mid-season and both teams might want to test each others’ weaknesses at full speed.

If I had to take a choice on which defense is stronger I would go with Real – on the other side if I had to choose if momentum were going to influence this game I reckon the strong supporter base of Seattle will pull them through.

If individual players are going to impact this game for Real Salt Lake I’d like to think it would be Ned Grabavoy or Joao Plata.

On the other hand if individual players are going to provide a positive impact to Seattle I can see Cooper or Martins taking that leadership; both can be dangerous goal scorers in different ways.

If I were in Seattle I would go to this game… just to watch two strong teams go head-to-head!
