I check FT attempted/48 for that, I never check just fouls/48.
I had a quite high fouling count last season and at the beginning of this season and our NT manager had probably the highest in all D2 (and he used to have a guy with 12 fouls/48 rate, although he doesn't have him anymore). It seems like in the last 2-3 weeks the number of fouls has subsided substantially for both of us. Probably it's just random, but maybe there is some reason behind it (GS link to stamina?).
I think this is the player you mean:
(23415818)This is the game I often reference in chat:
(62733008) In 7 minutes of play he managed to commit two flagrant fouls and was ejected.
Despite this he worked well for me. I have no problem with aggression. Its a pain when it's a trainee but you work around it. Or sell him.
The reason my team are committing less fouls is more to do with the turnover of players this last offseason, than any game related change.
