I'm not sure if he didn't want to compete for minutes, if he was just frustrated with his role this year, both or something else entirely.
But if he is worried about being recruited over then fine, leave. We're going to bring in a talented big man, we always have since we brought in Clingan with Adama. None of the other guys were scared of the competition, if he is he doesn't have the mental makeup I want in one of our bigs. He seemed soft and intimidated at times this year, especially at points in the tourney. Not trying to bash him that's just my honest assessment from afar.
As many are fond of saying on here... NEXT.
