My argument is that from the time he stepped foot on the court this season, he was out to put up whatever numbers he could regardless of what that meant to the team or the win column. I think he was a turnover machine. I think that once AJ and Sabol started having some growth in their game he intentionally did not pass them the ball. I believe his defense was non-existent. If a player will not buy in to a coaches philosophy, the coach can either suck up a lost season or bench them completely. In hindsight, I wouldn't be surprised if GH3 chose the benching. However, he has hours of video to show his future teams as to how NOT to play team basketball.
As to your total minutes item, he averaged 33 mpg this year and 29.7 mpg last year. He missed several games due to injury, so he would likely have surpassed that. I only mention that as you seem to be implying that GH3 failed to not play him enough this year. 22.8% on 3-Pointers with 149 attempts is deplorable for a Senior.
