The point being, you wanted to take a guy (Hurd) who has become an All-SEC caliber RB (in a VERY DEEP group of RBs no less), and play him at a position he'd never played before. Why?
Could Bo Jackson have made a helluva LB, QB, or Punter for some team? Sure he could, but he was a Heisman winner and elite, transcendent talent as a RB.
And as it relates to Gray...again, he doesn't even play RB in high school anymore, and has 78 total carries in his entire career. Why do you want to make him a RB in the SEC if he can't even make an impact at the position at the high school level? No school is recruiting him to play offense, and college coaches universally agree that he will play either S or LB at the next level. Do you know more than the coaching staffs at Tennessee, Florida St., Auburn, etc.? Your emphatic insistence that Gray will (without a doubt) play on the offensive side of the ball in college, suggests that, yet there is literally zero substance to that belief outside of your gut feeling.
