Although I agree that they need more depth at center, people seem to be forgetting that Garnett is a hell of a center too. When you consider the fact that there are very few big, pounding centers left (or at least ones that are any good), it really is not so bad to have Garnett at center. I have a feeling even if they did bring in someone else, unless they were a major upgrade (like Foster), Garnett will be getting a good deal of minutes as the center, with Powe or Big Baby as the PF...then they would adjust who is covering who depending on who they are playing against.
