Watching TNT, and while the camera was looking at other players, you could see him in the picture, and he was pretty clearly looking at the ref and saying "Why are you talking like that to me?"
Shortly after, I can hear him yelling over to the ref "You have no right to talk that way to me! No right!"
This was shortly after the Rockets (not the first time of the night by any stretch) seemingly earned a foul call and didn't get it, and Jeff was on the ref for it.
Methinks the ref cussed at JVG for saying something.
That really rubs me wrong. Big time. Bad enough that refs are incompetent, but to be rude to the coaches like that just because they question your call is crossing the line in my book.
