Seems like a fair enough deal.  Last year's stats probably favor the Drinkers, although I think that in a keeper league, I like Rondo's return.  I think Rondo and Bynum have the most upside; Deng and Blatche have, in my opinion, hit their ceilings (which are pretty darn respectable).
The big question marks will be Bledsoe's development, Bynum's health, and Blatche's role.
