Alright. I had some suspicions about this as well. Do you have similar information about stamina? Since I think an increase in stamina from let's say awful/inept to average/respectable might make a difference in fouls committed. Currently training a foul prone player and will see if my 2 weeks of stamina make a difference. At the moment he can't play 48 mins without fouling out.
