Great topic! But, I wonder if we've become a little spoiled from last year and early on this year with the talented depth that we have on this team. Those before me have pointed out "weaknesses" at guard depth, PF and center but not many teams (if any) out there have 3 serviceable centers and none have an extra MCW waiting on the bench in case the first MCW goes out.
The good news is, regardless of which position is currently our weakest, we are very likely to get stronger there. Right now Keita is our best performing all-around center but I feel that quite soon Coleman's offensive and rebounding abilities will far outweigh his defensive deficiencies. And, I think his defense too is bound to improve, hopefully sooner than later.
Our guard situation may be a little thin but it’s far from bleak. Of course we can ill afford to lose MCW for any length of time. It would be akin to losing Melo last year in that he is the one player that we cannot be an elite team without. But, I'm still comfortable with Triche at point when Michael needs a breather and he's played well at the 2 so far this year with some creativity, better control and getting to the rim. If Cooney can find any sort of offensive rhythm, he's already demonstrated fantastic defensive tenacity, we should be fine.
The PF is the true weak point right now. Rak is adequate and shows signs of progress and improvement but may not truly break through as a dominant 4 this year. I wonder if JB might experiment a little more with Coleman at the 4 and Rak and Keita splitting center duties.
As I see it, any one of these weaknesses could actually develop into a strength throughout this season. MCW has got to stay healthy and DC just needs to keep improving. We're much better off than most teams, by far.
