I think the fact that Bosh flat out refused to play in Cleveland made LeBron realize that even the King couldn't attract top talent to Cleveland. He's gone.
I still don't think Miami, I don't think he get the perception that he was in some way whatsoever riding Wade's coattails to a championship.
NY would spend like a mad dog to surround LeBron. He'd get Amare this year and Carmelo next(maybe).
Chicago would be a perfect choice I think. Rose, Noah, FA room. Sign and trade options with Deng. I think they have a better chance than most think.
NJ - eh don't think he wants to play in Newark. Not as nearly appealing as NY, Chi, or Mia.
