I have Houston winning 54-56 games with the Clippers breaking the 60 win mark.
Clippers will have a better regular season run, they will have more chemistry, a better coach and each player has a much more defined role, where Houston's rotation and roles are still mixed in the shuffle. I believe in the playoffs however that Houston may in fact be a much deadlier team as soon as they figure it out. Their defensive potential is quite scary to be quite honest.
But I believe Houston will go through a lot of adjustments which will hurt them in the long run. First, McHale still doesn't know how to properly use Asik and Dwight. Is he playing both together? How is this going to affect their offensive plan of attack? Defensively, they look ok against the Mavs, but obviously its a small sample and teams with quicker players will exploit them.
Next is Beverley and Lin, clearly both cannot have the same amount of playing time. I mean they could, but with a 3 guard rotation including Harden, one has to give. I think Beverley is better than Lin and he may eventually get more minutes than Lin, so how will Lin take this? I don't see Lin being happy with this situation although statistically, Harden and Lin produced better offensive numbers.
This year, Clippers will take the West no doubt. I'm pretty high on the new additions (Collison, Doc, Red ) and I believe DJ and Griffin will improve this year.
