1. Be sure you know the rules cold, but never, never, recite them to the coach.

It's too show-off-y. If I think a coach really wants to know the exact rule, I'll say, "I'll show you after the game." They almost never remember later, but the ones who do are usually the good ones that want to get better, so it's not a problem.
A few times I've said, "Coach, it's Rule 2-10." or "The exact wording is in the Live Ball/Dead Ball rule." This quiets them down without making them angry. Usually.
