Back to the OP:
Until you know all the coaches and they know you, I'd recommend against sarcasm, facetiousness, and other forms of irony. If they joke with you before the game, you can feel free to joke back, but on the floor it almost never plays well.
If a coach makes a comment that gets a rule wrong, I won't argue with him about it. Learn the useful expression: "That's not the rule, coach."
When you say that, be right about it.
