I think that his utmost ceiling would be a Shawn Marion type of playstyle. Amazing feel for the game, makes good passes, can lock down people between 2-4, and can knock down shots at a respectable rate. If everything pans out you are looking at an awesome team first player. The perfect 4th of 5th guy in a sense.
Like others here, I am afraid of his wingspan. He is obviously a freak athlete, but his measurables make him an explosive wing in terms of size. In the modern day you want the opposite. You want a PF with SF skills, not a big SF with PF/C skills.
Edit: Wow his standing reach is an inch shorter than Hoods, and 6 inches less than Faried who I consider undersized. That's scary.
