I agree with your manager development philosophy but not every manager failure is created equal. Failing to identify a weakness in a kid’s game or having a suboptimal game plan is different from allowing a scumbag into your inner circle. I’m not sure you ever learn your way thru having bad judgment like that. We passed on the latest chance to give him the eject button so the AD either believes the nonsense is permanently ended or he had no choice, we were unprepared again, etc.
A couple of points about the Ron Bell situation:
First of all, despite the sensational nature of the episode, it really didn't do a lot of harm to the program in the practical sense. Yes, it was embarrassing, but the GTAA hired out an independent investigation on Bell's allegations, the NCAA investigated the matter and pretty much the conclusions are all the same, it mostly was an embarrassment intentionally created by a sycophant and blackmailer. Enticing Okogie and Tadric to swim in a pool in Arizona was a minor deal and the NCAA seemed pretty satisfied with the suspensions we handed out. Not a shining moment, but hardly the catastrophe that some GT people are making it out to be (especially relative to some of the malfeasance being discussed by the Feds or UNC's academic fraud deal).
Second, I hope that most people here have not had run-ins with duplicitous people. For those who have never been the target of cunning people with no ethics, then I can see where you might find scenarios like this inexcusable. But the truth is that there are people out there who can fool you. While it is human nature to want to blame the victim, sometimes they are really innocent. You assume that you would be able to spot the scumbag, and may the grace of God protect you in such an assumption.
Third, Pastner's innocence regarding Ron Bell is substantiated not only by the finding of two independent investigations but by the extensive history of Ron Bell's freakiness. That guy is not worth roasting one of our own over. Hes a bad actor, pure and simple. If you will turn on our coach because of Ron Bell, then you seriously need to question your sense of loyalty.
(Same for the NCAA. if we roast one of our own based on the pathetically unjust NCAA then we have to seriously question our own judgment.)
