It wouldn't hurt to see a fouls drawn stat imo as that probably would show if there actually are any positive aides the an aggressive player.
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?).
