Memphis-I'd say you have a team that might do well in the regular season, even possibly as you say, winning the division. However due to your roster construction do you think you're going to flounder greatly in the playoffs?
DJ White and Brook Lopez can't possibly be expected to perform favorably as second year players, their first time in the playoffs, against the best offensive post players in the league (who are mostly in the West. Holla!). Once the pace slows down, and you need to re-evaluate whether or not Boris Diaw is helping or hurting you in the half court, it looks like you're going to be consistently out-rebounded.
Also, while I'm high on the potential of Chandler and Rudy F, I'm not as high on them right away. I actually like Mo Williams for you, and I think you're overlooking the benefits of running small with Mo AND Tony in the back court at the same time, and I do think that Tony Parker is capable of powering a team with flaws to the playoffs, as long as they can run (which yours can), I just don't know how far you're going to get if you get ot the post season.
