He has already said that he will use this summer for experience and then return to college for his senior year. He can definitely make it, he's still a decent prospect and is on some mock drafts for 08.
His biggest problem is that his team has gone no where in the past couple of years. They started off pretty well in non-conference, but then it fell apart during the Big 12.
Like Daneo said, he battled injuries (I believe stress fractures in his foot and dislocated fingers) throughout his Soph. year, yet still played pretty decently.
He is part of a four guard rotation where he doesn't get enough opportunities. He'll score 20 one game, then dish 8 assists the next, he just hasn't been able to put them together regularly.
If he can get his name out there some more through these workouts, then put together a consistent season at Baylor (and have a decent W-L record) he can make it for sure.
