wow really? Did soccer also go through a statistical revolution? I don't watch soccer at all and am pretty surprised to hear this. Did all the teams converge on a winning solution?
because of the structure of soccer (completely different to basketball, it is an invasion sport but statistically very dissimilar), it has completely reversed the ordering of the sport
there is significantly more strategic diversity, and teams that were unable to compete ten years ago are now able to compete effectively with wealthier teams (there is no catchup mechanic in soccer unlike US sports, ffp rules have also played a role but in the EPL at least the primary factor has been smaller teams using their budget more effectively)
the most recent changes have been: premium for coaches (distinct from managers) has increased significantly and a greater focus on set pieces (but this is going back to the future, twenty years ago EPL had a period where teams did this to level the field...today, they are doing this and it appears to be permanent).
it is also worth adding, i would say the majority of clubs that have tried a naive statistical approach have failed. Liverpool tried and are leading but are completely reliant on one player, Arsenal are doing better but reliant on set plays and their recruitment has been poor (they have had a stats team for over ten years at this point), the teams that have done well with stats (Brighton and Brentford) have a hybrid approach (and Brighton is further down the road with this, and have done significantly better...they use non-public resources far better, integrated with sport science, etc.)
if stats in soccer is a 90-minute game, we are still at minute 5
he has changed strategy multiple times based on team composition
possession-based at Barca, more pragmatic at Bayern, first City teams used wing-backs and insane attacking then acquired more defensive players and went back to suffocating opposition
playing out from the back is ludicrous only because teams who are unable to play that way insist on doing it, and the credibility of that strategy as a global minima has already passed (largely due to the issues Burnley had last year and Spurs/Southampton had this year)
this year has proved that there are multiple ways to win. imo, the most boring manager is Arteta who does the defensive stuff without (almost) any attacking players (and is, thankfully, failing...the worst thing would be a manager playing like a Serie A side and winning)
Pretty much all teams play more or less the same style of building up with the goalkeeper because data shows that even though you suffer more goals it's offset by scoring more.
But still data-lization is taking the fun out of basketball, that's for sure.
