I think it's different for rules versus judgement. If I wish I had a judgement call back I'll tell the coach that if I think he needs to know. Sometimes they don't complain at all, when that happens I don't say anything cuz I don't need to.

If I kick a rule though and I know it I am more likely to admit I kicked it. I kicked a rule last year, looked up the rule at halftime. When I came back out to the floor the coach was standing there holding the rulebook. I stopped him before he said anything and told him I kicked it. He shook my hand and we moved on. And no I did not T him for standing there with the book waiting for me. Still wouldn't.
