A lot of the analysis is very fair, his closeouts were very poor. I will say defending OBI's around the rim defense that a scout this year may not necessarily see is that he was making concerted efforts not to foul.
His freshman year he was in foul trouble all the time. This year there may have only been 1 or 2 games where he had any foul trouble or worried about fouling out. I think he'll be able to find some middle ground being more physical on defense and not worrying about fouling as much.
