I agree with MR to an extent, but I personally believe this should be a decision left up to the parents and their child. If they're physically and mentally capable, and they're ready to go to college, then I don't see the issue, particularly if they've finished all the required course work for graduation. We allow students to excel in the classroom and jump to college early. I don't see much of a difference if they want to give up their high school spring and get a head start on their careers.
I don't think a player has ever given up their entire senior season to jump to college, nor do I think it is possible, but perhaps it has happened. Truthfully, it wouldn't be a very wise decision considering most people would be grossly under-developed in comparison to their classmates in the same class.
