I guess I'll just agree to disagree with you on a couple of points you made. First, he is not 6'9". He's 6'8" at best and that's with shoes on. Stood next to him in both slides and in his game shoes this weekend, and he's not 6'9".
Also, he is plenty crafty enough to make up for his lack of quickness to play the point on offense, though there's no way he defends at the one or even the two in a league like the Big12. He can, however, defend the three. He would be the ideal "point-forward" in college. Absolutely positive he can do that at the mid-major level, and probably at a high-major in the right offensive system.
His jump shot is much better than people give him credit for. The real issue is his decision making on offense. He still does not show the consistent ability to know when to shoot and when to pass. He often times errs on the side of being too unselfish when the situation calls for him to take over - especially in school ball. He owns way more game than he shows most of the time.
All of that said, I don't think he'd be a good fit for an Oklahoma or a Texas, but could possibly be a good fit for a West Virginia-type team.
