Ask coach if he wants a time-out on a made basket?

Better to just glance over at the coach, and be ready to acknowledge TO immediately. Accomplishes the same thing.

And what happens if the other coach expects the same thing but for some reason you get caught the next time down the court and can't do it? Gives him an excuse to howl.

I don't think we should be initiating any more conversation with the coaches than is absolutely necessary. Always be receptive and approachable, of course, but let them initiate.
