He's got a chance to someday play in the NBA. Test the waters now, see what the NBA scouts are saying, I think you can even go through some pre-draft workouts, and see where you stand. Then when you find out you aren't ready, come back and work on the weaknesses they identify for you and be ready for next year. And if he's better than I think he is and just wows them and looks like he has a legitimate chance to be a 1st round pick, go for it.
