Then get him to stop yelling - "Coach, I'm going to talk to you man to man, there's no need for you to yell at me."

Then find out what his question is - "Coach, is there a question you have for me?"

He'll probably say "Yeah, why are you talking to my player?"

Then you answer "Because it's part of my job here" and walk away.

If he yells or follows you then T him.

I agree with Dan. Walk the coach back to the bench, let him say his piece. At the point he stops or asks you a question, tell him, "Coach, I told both players to knock it off and play ball. It's part of officiating. If you don't want me talking to your players, that's fine. I'll just hit him with the foul or the T next time." Turn and walk away. If he chases you, pop him.

But do not allow a coach to come onto the floor to confront you.
