Points = fouls!

[CoachCER]

I think you have the right picture, and honestly, he created enough of a disturbance with refusing to leave the gym initially that I was surprised the game wasn't forfeited.
It was a competitive game and it was in the 4th, and my guess was these guys didn't want to let the actions of a loose cannon take anything away from the boys. This was a while back (longer than I initially thought - 2002), but I think some action was taken by the school against this coach. I am fairly certain he was not back the next year.
(Of course, I wasn't back either. Note to self: when coaching at a private Christian school, never, ever sit the minister's kid on the bench. Same for the principal's kid. Only coaching job I was ever fired from, and it was after taking the team to the semis of a 16-team league for the first time in school history.)
