Big T - you can ignore a coach on pretty much all comments. You should judge when a line has been crossed.

If he asks a question, and its legit and you have an opportunity, try and respond. Keep it brief and basketball only. Only speak in fact, no "I think I saw that."

You really have to feel what's right for you and no one here can tell you when and where you should address a coach. It's different for everyone and 2 officials can have the same coach, same comment and respond with the same phrase and get a different reaction.

Treat them like any other person (adult or child) and sometimes you need to punish them like a kid (because they can act like it).
