I understand the times, but there is NO WAY a referee should ever be mic'd up... never. The best refs/umps are those that you can't remember their name when the game was over. The NBA has, IMO, had the most flamboyant refs (Earl Strom was a showman) and I believe it's a dangerous line to cross.
Sheed had a problem, no doubt. His mouth and attitude did him in many times. But when you see this video you come to see just how much of this is PERSONAL, and it shouldn't be. A ref has to show maturity in the face of stupidity, and if he just walked away then Sheed would just turn around and do the same.
