I don't care what anyone says IMO Lebron will be even more successful winning in NY! To get endorsements you have to not only win but be marketable youself as well. Lebron has that star appeal. There's so much money in the metro area alone that he'd see a spike just from being here.
As for BB I think we can give him a great shot to win as we don't fear spending to add what we need to improve. Few other teams are as willing to spend. Cap space in 2011 is a huge plus IMO.
