Playing style
How Bartosz Piotr Grzelak's teams play vs league-season peers (2016+)
Descriptive — how a coach's teams play, not how good they are.
Career average
One shape blending all 3 clubs (2016+).
The baseline — each polygon on the right shows how one club's style deviates from this.
+0.14style consistency across 3 clubs
More consistent than 47% of multi-club coaches.
A high score means the same playing style travels from club to club — well above the random-coach baseline (-0.01), so it's a signature, not the squads.
