John Wall.
Haha, sorry, I had to. If it were only this year's draft class, it would almost be a lock. Griffin could challenge him though. Splitter could turn out to be a more effective player, but won't have the numbers to win it. Evan Turner is the other guy I think could challenge. He seems to be a ball dominator which bodes well for counting stats which basically rules the ROY voting. I've never seen Paul George play, but he seems to be on the right type of team to get a chance to put up big #'s. Also Jordan Crawford could surprise people in New Jersey. Cousins I think will be very good, but not ROY good.
