That move he repeatedly displays where he literally steps out of his mans way, then lazily swipes at the ball as his man blows past him towards the hoop, has got to be the most appalling defense I've ever seen.
Its true though, he HAS shown the ability to play quality defense, but Steve is right. Houston turned the reigns of their offense to him, he has no accountability on D and no one to take his minutes should he fail.
Mentally, he does not seem like the kind of guy to lead a team to glory. Taking plays off, all the flopping, his line about him and Dwight being all that matters for Houston and everyone else is role players. I mean... I'm sure a TON of stars feel that way but you cannot say that. I'd think between him selling teammates out on D and then marginalizing them in the press, he probably has a lot of dudes in that locker room who do not like him very much.
