NCAA rules
If the ball didn't have a chance to go in, it's not GT even if it contacted the backboard with part of it above the rim. I watched the replay and thought was a good no-call followed by, of course, the usual cluelessness from the commentators.
And a well-deserved whack for McCaffery. He's pathetic. And, he yelled at the wrong official. The L doesn't call GT. Wait, coaches don't know that?
