The APR is just an excuse to take the high road on the way out. AO doesn't think he has been treated fairly and wants away. And, frankly, if any of us were in AO's shoes we'd want out as well.
This will come over as criticism as Calhoun, and it's not meant to be, because JC hs the right to try to get everyone to reach their potential as opposed to just winning games, or being fair, and because he has three rings in Storrs CT and the thought of me criticizing him for anything basketball related is absurd.
Having said that, look at what happened this year through AO's eyes. He walked in to camp and had his position given away, and was in a fight for playing time, notwithstanding the fact that he was at worst the third most important player in a run to Big East and National championships. But from the first day of practice, it looked to him as if he had to totally adjust his game to Drummond's potential, notwithstanding the fact that Drummond had neither accomplished anything for UConn nor shown that he possessed any basketball skills whatsoever (as opposed to athleticism, height and potential). So AO sulked, didn't truly play hard, lost more playing time to TO (who was simply not as good a player) and sulked some more. Than, about half way through the season, he started playing hard. Didn't put up great numbers, because he never did figure out how to do so alongside Drummond, but he played hard every night and guess what happened -- for all the complaining here, the team over the last 12 to 15 games was significantly better with him on the court than with AD, and was worlds better with him on the court than TO. And yet, he was never given the "leash" that Drummond had, and wasn't even put back on the floor as, over the second half of the season, run after run after run came against us when he was out.
I am not saying AO was blame free in this. He should have adjusted more and sulked less. He should have stayed off twitter. And he should have ordered his family to leave his career along. But if any of us were him, we would not in a million years have thought we were treated "fairly" and many of us would be doing what he is doing and looking elsewhere. The fact that he's doing it without trashing anyone on the way out is to his credit.
