Earlier this season, I had a player with 4 fouls going into half-time. I talked with my partner and we both agreed he's gonna foul out within the first few minutes of the 2nd half. To our surprised, he played most of the 2nd half and did not get one foul. If I remember correctly, I think he even drew a charge!
Only had a couple of fouled-out players this season, but all were in the 3rd or 4th quarter. I can only think of one time in my career when I had a fouled-out player, two or three years ago in biddy wreck. This kid couldn't play defense to save his life, probably didn't know what defense was. He would constantly hit the other players arms, grab a hold of them going for the ball, etc. I gave him a lot of leeway just to see him make it to the 2nd half, but it didn't happen. Other games I did with him playing he would just barely make it to half-time, just to foul out in the beginning of the 3rd quarter.
