I coached a touted player (RB/LB) that had spinal stenosis (the same condition as Jones), and it's a pretty scary condition for a football player. I'm not sure how bad Jones has it, but my player couldn't even get medically cleared to play in college. One doctor told us that one bad hit could paralyze him, and that was the end of his playing career. With the impact that NFL players hit with, I don't know if I would spend a top 10 pick on that kind of risk.
