PSR has underlined how badly run most of them are.

This post is about 'possession adjusting' defensive stats, but really it's about - exorcising past demons - the extent to which making player statistics comparable to each other is a science vs a craft - extended metaphors get-goalside-newsletter-archive.beehiiv.com/p/possession...

Possession is not nine-tenths: analysis into possession adjusting

Defensive statistics in football are difficult to parse. Is adjusting for a team's possession share the answer? And can data for players ever fully be comparable?

I'd say, don't look too much into where Coventry are this season as a measure of Robins as a manager. I'm not saying it's perfect or even that it could work at Stoke, but simulating all Championship shots this season 100,000 times, Coventry are not a bottom half side.

On performances, you really can’t argue with that as a sacking.

From the piece I wrote on Schumacher's sacking: "For my pessimistic side it feels inevitable that this ends as every other revolution has, first a sacked Head Coach & a new style of play, then a sacked Sporting Director and promises of a ‘new approach’ & ‘lessons learned’." 1/2

Just to update: Since relegation, Stoke have had: 4 Managers 2 Head Coaches (soon 3) 12 Assistant Managers (soon to be 13) 1 'Technical Board' 1 Sporting Director 3 Technical Directors 1 Director of Football 1 Head of Football Operations 2 Chief Scouts 2 Heads of Recruitment

Domination from Leeds. Stoke's inability to cover passing lanes out of possession exposed by a quality side.

Choupo-Moting is the latest in a surprising run of Stoke City's 2017-18 squad coming to MLS: - Xherdan Shaqiri - Ryan Shawcross - Geoff Cameron - Tom Edwards - Bojan Krkić - Eric Maxim Choupo-Moting Stoke finished 19th that year. More awestruck by this trend than the mid-2010s Barcelona pipeline.

As far as I can find, no Championship goalkeeper since they started recording Post-shot xG - a measure of how difficult a shot is to save - has come close to how good Viktor Johansson has been for Stoke this season. An average shot-stopper would have conceded *11* more goals this season than he has

Potterlytics @potterlytics.bsky.social · 15/12/2024

An upcoming piece this week. It won't be nice, but just as a quick preview: I simulated every shot in the Championship 100,000 times: In *99,700* of those simulations, Stoke conceded more goals than in real life. A mixture of luck & Johansson, you can't rely on those forever.

Well, If you're wondering why Stoke fans are so concerned, and wondering why Narcís Pèlach had to come out and say he was changing some things in the defensive structure, erm... This is why. That spike in xG against is gigantic, on already appalling underlying numbers.

Absolutely great to see Arsenal playing with a rest defence made up entirely of 6’+ centre halves, a couple of quick wingers and scoring through blocking in set pieces. Pulis laughing.gif

Spotted that Tom Cannon has been nominated for Player of the Month. His shots & passes for November below. I'm not really sure I get this nomination from my end. 3 open play big chances, just the one open play goal. Not awful, but is it award-worthy? Can't look past Borja Sainz for this, surely?

Delighted to announce two new features on my web app! championshipdata.streamlit.app Chalkboard: Show passes with arrows on a pitch. Fully customisable data as shown below! Heatmap: Show the start/endpoints of passes as a coloured heatmap, compared with the league average or just with other zones

Update to championshipdata.streamlit.app! Check out the new chalkboard maps for passes, and the heat maps too! Any comments and help appreciated, now to work on streamlining it all and getting that processing speed up.

A switch to a back 3 today. Extra centre back probably indicated more focus on defending the box, and allows a bit more freedom for Bocat/Tchamadeu with Stevens still recovering from Tuesday's game. Big test for Pèlach's defensive plans, can they do it against a top side?

A couple of really useful bits of info here on Stoke's lack of intensity and over-willingness to drop into a low block. 4th lowest PPDA (allow the opponent to pass the ball in their own 2/3rds more than all but 3 teams before challenging), 3rd lowest field tilt, lots of defending in their own 3rd

Stoke are in a bit of an interesting spell at the minute, and there are some big questions to answer. Whilst Stoke have only lost once in their last 8 league games, the rolling xG average plot shows their underlying numbers look pretty poor since Pèlach took over, even given the v small sample size

This! This! This! My biggest issue with everything Stoke have done the past decade in a nutshell. The transition from the manager setting the vision to the DoF is an improvement, but it’s still a fundamental misunderstanding of what a DoF is for.
