When Pro Bowl running back Jamaal Charles was lost for the season in Week 2, it left a black hole in the Chiefs' ground game.
KC has since gone to a running back-by-committee system where backups Jackie Battle, Thomas Jones and Dexter McCluster now get more touches.
So far, Battle has been the only one who has made much noise this year, as he had over 100 rushing yards against the Colts last week.
It really doesn't matter who gets the job done against Oakland this weekend, but someone needs to step up and give KC a solid weapon in the ground game, in order to open up things for QB Matt Cassel and the offense.
