If the kid is good enough to go and make NBA money...why would you not root/encourage them to do so. Kid can always come back to school but I'm pretty sure the change to play in the NBA is at best a one in a million opportunity.
Andrew is the better PRO prospect. I like Aaron and am glad we have him but 6'5" shooters are a dime a dozen in the league. No way Aaron is a 1st rounder.
