Here they are in terms of probability (my Opinion)
2) Brooklyn Nets
I didn't list the Lakers because Dwight already said he doesn't want to come to LA and be second fiddle to Kobe. And Jim Buss doesn't want to give up Bynum for Dwight unless he is sure to get a long-term commitment from Dwight and that ain't happening.
Rockets are most likely destination now because they don't care as much about signing Dwight to a long-term contract, unlike LA. They will accept fewer years from Dwight on a contractual basis. And are currently making a lot of noise in trying to sign Dwight.
I had the Nets at 2 and Mavs at 3, but really they are kinda tied. Dwight will go to the one where Deron goes, if Orlando doesn't trade him. It is simply because Dwight is chasing a championship and has indicated his desire to team up with Deron.
If all else fails, he is back with Orlando. However, I just don't see that happening.
