**AT** school. Not **FOR** school. I've watched a bit of basketball at various times (mostly olympics) but surely you'll admit that there is a very limited amount of tackling?
I kept getting picked to play at school because I was tall. Absolutely hated it. Everything you instinctively tried to do resulted in the whistle being blown. The problem seemed to be that there were hardly any legitimate ways of winning the ball back from the opposition, hence the "your turn"...
