I think the biggest problem for Davis is that he is now playing every night, despite the matchups. He is always going to have trouble if he gets trapped in tight, but against certain matchups (like the Wizards), he can be completely useless offensively, because of their length. In the past, they had Powe to even that out, but unfortunately, that is not the case anymore, and Shelden has not proven to have a well rounded enough game to help any more against those teams.
