LeBron and Bosh to Chicago makes a lot of sense if they want to win a championship (or multiple ones) but I still have a hard time seeing LeBron play in Chicago, in Jordan's shadow. With that said, he has already stated that he would wear #6 so it leans towards Chicago too.
I think LeBron and Bosh go to Chicago, Stoudemire and Joe Johnson to Miami, Rudy Gay to NJ, and then every team fills out their roster with role players willing to take discount prices (especially in Chicago).
And to think that Thibs will probably coach a starting 5 of Rose/role player/LeBron/Bosh/Noah... wow, scary.
