It will be almost impossible to do but with Sully going down I don't see how we trade anyone out of the rotation and get a good big. Best bet is to find a better big free agent or dislodge someone with matching salaries and draft picks. I don't see how any of this bunch is expendable now:
c KG Wilcox
F Bass
F PP Green
G Lee Terry
G Bradley Barbosa
I mean there is no sense in sending Bass away and you get someone very obviously better than he is, if the idea is to help KG up front
Meanwhile, Doc isn't play Wilcox much so its hard to be confident a lateral move will help.
If we can send others plus picks and get a decent guy ok but I have no idea who that is
