18. James Conner
When Le’Veon Bell did not report to the Steelers this season, it was unclear if they would be able to get any production from the running back position.
Then in Week 1 James Conner rushed for 135 yards and two touchdowns, putting any of those concerns aside. Conner has gone on to have five 100-yard rushing games this season and has become one of the best running backs in the NFL.
