Taking the Nolan situation one step further, it seems probable that he is frustrated by the lack of attention given to Colorado by the fans and the media.  He's probably thinking he'd have two MVP trophies by now if he played in a major market.  Even with a perennial contender here, I'm not sure he would stay.  I hope I'm wrong, but Nolan's also never really expressed a desire to play for the same team during his career like Tulo did.
