5. Ameer Abdullah, Detroit Lions running back:Joique Bell has been one of the NFL's slowest running backs this season, averaging a paltry 1.1 yards per carry and 2.44 yards per touch. Abdullah, on the other hand, is generating 5.5 yards per touch with a pair of touchdowns. It's time for embattled play-caller Joe Lombardi to start leaning on Abdullah as his featured back.
