I've had two games where one of my positions got a lot of fouls (once at PF and once at PG). Both times the starter and back-up had 3 fouls by half. In the first game I got a lot of fouls in General but only two guys got in trouble. In the second game there were a low number of fouls. None of the guys has foul trouble history which made me think that maybe the strategy or player they were guarding had something to do with it (just theory, no proof). The first time I was running a 3-2 and the second time a 2-3. I thought maybe the first time the guys down low were under pressure due to my emphasis guarding people outside and vice versa the second time. My other thought about it being the guy they were guarding is due to the fact that it happened at just one position both times.
Just a thought
No matter where you go, there you are.
