I wouldn't put my chances on foul prone player, If I keep him would be as a role player or a sub. I had this PG that draw 3, 4 fouls every game. THat wasn't bad. Until he fouled out on final matches. Given that he was very important in my offense, I sold him and got another.
It's up to you but I wouldn't hace a foul prone player as any of my top 3 or 5 players... Lost too many finals, learned the hard way =(
