Cooling off

[jmkbball]

I would not go out of my way to say something to him...chances are, his attitude and mouth have joined his officiating abilities and most people recognize that.
That said however, I would have a hard time not saying something if a private opportunity ever offered itself...that you've heard from others what he has said and it bother you. You considered him a friend and the comments don't reflect well on him or your perceived friendship.
--just two cents and good luck.
