I would go with the Bulls too...by a long, long shot.
Knicks? C'mon, this off-season so far is a disaster for them. Amar'e is great, but losing Lee is a major loss, and who else do they have? If they manage to get CP3, I'll change my assessment. They really need both Paul and Melo to compete for the East.
Bucks made some nice moves, but still they don't have an ultra-elite star which I think is necessary to get to the Finals.
Utah? You've got to be kidding. Boozer is a FAR BETTER player than Jefferson at this point.
