Regarding the OP.
Whether you take time off the clock isn't really relevant to the coach's rant. He's flat our wrong about the rule, and he's wrong to go ballistic. If he's been a howler monkey already, this is a good spot for a T. If you want to be nice, "Coach, I understand you disagree with me on the rule, but I can't have you yelling at me."

On your second situation, I'd be tempted to let him know that he's now incorrectly challenged me on two rules in the same game, and I have a three strikes policy. In reality, I would have already talked to him after the first incident about proper behavior or I would have T'd him; either way, he's less likely to get stupid here. If he does, easy T.
