I typed this bigass post yesterday and my computer logged me out.
Basically, if we really do need another backup 1, get someone like House or Dixon who can play stretches at the 1 and stretches at the 2. We need "short swingmen" depth, because we pretty much have Felton and Bell. Bell is old and might have a couple of old man injuries, Felton is a point and inconsistent at shooting guard.
We should probably draft an SG prospect, but if we don't go after a young player like Von Wafer, Green, Head and hope it works out. I don't quite know what is within our grasp.
As far as the big man, guys like Lee, Villa, Millsap will all be available. Now, since Diaw is undisputed, I think we shouldn't go after those guys. But since they are all on the market a guy like Wilcox might come for less than you expect.
