For low money, why not? Seriously, we have Clifford Ray and KG to steer him in the right direction and make him focus on a couple key things to do defensively.
Low expectations, low money, some upside. It should be painfully obvious that we need 7+ footers for times like the 2010 Finals. No matter how much you like or dislike certain players, we MUST bring in some from the 7+ ft crew. Therefore, Sweetney, Sheldon and anyone in the shorter than 7+ ft category is out of the conversation.
It's all about getting some guys to protect the rim and match up with other bigs. Kwame could certainly handle some of those chores if he put his mind to it and was given proper direction.
