Don't talk to my player

[Dan_ref]

First, get him off the court - "coach, I can't have you on the floor, you know that".

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.
