Hawks Coach,
Sorry, but I didn't see the call in question.
Mark,
I personally have never called it.
Second, I would interpret it to mean head coach and/or players. But Hawks Coach does bring up a good point.
The rule prohibits inciting an UNDESIREABLE reaction.
Even though I think I would take offense as an official
at what "K" did becase IMO he was showing up the officials,
I have to admit that getting your crowd pumped up can be a tremendous advantage for the home team, and that's why playing at places like Cameron Indoor is so touqh.
Now, if the Coach starts leading the "Referee,Referee,B-A-S-T-A-R-D" cheer........
And if you "t"up a coach and say "you were inciting an undesirable action," you'd better be prepared to run him!
