AA would certainly help, but let's remember a couple of things. First, he is an awful defensive player whose weaknesses were often covered up by Zeke erasing his mistakes. Second, AA had trouble getting into shape when he was active. I can't imagine what shape he is in now, what commitment he would make to getting back into shape, or how long it would take him.
Also, I am not sure we could trust him. He not only got himself in to trouble, but then compounded it with a probation violation when he still had a chance to get back to the team.
