The only reason i would t him is because of a past experience.
It was at my first camp, and I was still a fairly new naieve official
.
I was working a game, and there was an obvious charge deep in my partner's area, the only reason i saw it, was because all the players were grouped down there, and I was watching in the key for some rough off ball contact.
My partner didn't call anything, and the coach of the defensive team as the play is moving to the other end of the court purposely falls to imitate what his player did when he was charged. Neither my partner nor I made a call.
After the game, we got a good explanation of when to draw the line. And never again have a let a coach get anywhere close to that level.
I this is probably why I have such a low tolerance for coaches.
