Jones will fall lower than the 3rd. You take a risk on him in the 4th or 5th, because that's when teams will start looking at him. But outside of New England, it's hard to picture a team willing to use a second day pick on a player who will provide them no benefit until 2018 at the earliest.
After the Maurice Clarett, I'm shocked that anyone would want Denver to take a risk on a character running back in the 3rd. Denver should never be allowed to use a 3rd round pick on an RB with character concerns because of that pick.
