AUBURN, Ala. — Nick Marshall’s feats with his feet are well-documented. Sure, many quarterbacks can extend plays and make something out of nothing thanks to fancy footwork. But few have shown the ability to excel at Marshall’s level. Take a look at the 1,095 yards he ran for last year in junior college. Also take note of the 19 touchdowns he accounted for on the ground, the second-most of any player in the National Junior College Athletic Association in 2012.
