No player in our top-10 is more unproven than Montee Ball, but then again, none are in quite as good of a situation. Playing the side-car role to Peyton Manning in the Denver offense is an ideal place to be for a running back, and Ball steps into that role with very little competition in 2014. So despite having only a few dozen touches in his NFL career, his consistency as a runner should keep him on the field for one of the best offenses in recent history. That consistency led to a Success Rate (the amount of carries in which positive NEP was earned) that ranked in the top-three among backs with 100 or more carries last year.
