what would you do?

I'd probably let the coach take care of it. Make him aware of the situation and most would chew the kid out. Another option would be to have game management remove him. If he's not on the team playing, he's a fan on the floor. Have him removed. Also, could you assume he's an assistant coach since he's not in the book but clearly with the team? I know its a stretch, but this is an odd situation. I'd go with my first option of letting the coach handle it, but its always good to talk about other ways of handling things.
