I don't think he is leaving Orlando because he doesn't like Orlando. I think it's because they have terrible managment. Would you really want to play somewhere that gave Rashard Lewis and Hedo Turkolgu ridiculous contracts? Also someone that traded FOR Gilbert Arenas?
I think he wants to leave for 2 reasons - 1 because the team around him and he wants to win - 2 becuase he wants to be in a bigger market = more endorsements
