I don't want him.
If Ainge and Stevens meet with him and decide he'll be ok and he'll accept a bench role, then I'll give him a chance to prove me wrong. But based on what I know about his presence in the locker room I don't want him.
If he were to come, I don't want him displacing anyone in the starting lineup. Maybe he's the first or second player off the bench, but he has to know that his role is to be a rich man's Aron Baynes. Set hard picks, rebound, protect the rim, and he'd better be good at those things because he can't shoot the mid range shot Baynes can. Obviously he'll be better around the rim but Howard changes the spacing a little.
