Rock Barnes was hired for stability. For all his shortcomings, he has brought that to the program. He will win a good amount if games and recruit well. He won't cause controversy or bring NCAA investigations. Atthe time of his hiring, that was what we needed. For those reasons, he has a very long leash.
That being said, he will never be a threat to win a championship. I feel that if Danny White feels like he can get someone better, he has the balls to do it. He just has to wait until the shortcomings become loud enough to rip off the bandaid. Barnes is almost 70 and underperforming based on expectations. For every year he doesn't make a tournament run, especially considering his recruiting success and expectations, his leash gets a little shorter. His age also starts to become a factor. He will be here for another couple of years at least (unless he retires unexpectedly) but if he hasn't made a tournament run in the next two years, he may not see a third year in his early 70s.
