Basically, yes, I'm posting a line of thought that Mike Greenberg read on Mike & Mike, but it makes sense, so I wanted it up here. 

Basically, here is how it goes.

1) Chris Bosh wanted to play with LeBron, more than Dwyane Wade.

2) If LeBron wanted to play in Chicago, Chicago had the best pieces for a package in a S&T for Bosh.

3) So basically, since Bosh is going to Miami, with Wade, that means LeBron doesn't want to play in Chicago.  If he did, Bosh would be going with him, instead of to Miami with Wade

Also, I don't see him going to Miami now either - Bosh is completely opposed to taking less money, he's made that pretty clear, so that alone seems to eliminate that option.  Plus, LeBron would be "joining" the Great DWade in Miami, as opposed to bringing his greatness to a team that doesn't have a player of Wade's caliber. 

IMO, This leaves just returning to Cleveland, or coming to New York.  Tomorrow at 9pm should be pretty fun!
