Has this guy done anything besides dunk and shoot layups? I've never seen it. Of course I only see the highlights so I'm not sure if he can do anything else.
If you watch the play by play of their last win in Chicago, or any full game, you would easily see that he's not just a dunker - He already has a very diversified offensive game. He has a pretty decent midrange game, some very nice post/spin moves, can lead a fast break, is an excellent passer and is a very good rebounder.
I think that, first and foremost, rookie mistakes and injuries have hurt the Clippers this year. They've also had one of the most difficult schedules to start. You should see their record slowly rise as their schedule eases up.
