No need for a center. It's that simple, the league is going in a direction that as long as you have a few spare long arms (Steamer), some athleticism (Wilcox), some skill (KG) and a wide body (Sully), the combination of the four makes up for the lack of true skilled center. Look at the Heat; I know their talent level is off the charts, but they just won an NBA championship with Battier, LBJ and Bosh as really their only frontcourt. Battier/LBJ are 3s and Bosh is a 4. A tall four but so is KG... What does that tell you about the direction the league is headed?
A true center would be nice but no more than a luxury, certainly not a need. We have KG, Sully and Melo, made an offer to Stiemsma; make an offer to Wilcox and we'll be good.
