I don't think it hurts NCAA as much just due to the fact that the prospects won't last long. 5 years at the most then they move on. Plus I think college is driven more by potential than professional. In college a coach is likely to change his scheme to fit in a high potenial guy. Look at Mack Brown and Texas they have altered their system to utilize his QB's strengths. I can't really think of an NFL team changing an entire scheme to fit in one player.
