Since I mentioned Blair, lets go to that point.
I stated early on that DeJuan should be watching as much tape on Chuck Hayes as possible. They're of a similar size and center of gravity, and there's really no one better than Hayes in the post defensively at his size.
But becoming that kind of player is going to take time. Blair's never been the great defender I've seen mentioned. He's got great feet and strength, and those long arms will only help in his quest to become a solid defender, but he's also a notoriously foul-prone player who also happens to be a rookie; pinning your hopes on Blair being the answer defensively, this year, after watching the Rockets success last year, just isn't all that wise or even fair to DeJuan.
Blair should be looked at as an X-factor coming off the bench and asked to be nothing more than what he is; a huge asset on the boards and on the offense, but a defensive liability against the elite-level teams.
