That they went with an in-house option, Spencer Ware, to replace the injured Jamaal Charles on their roster, would seem to speak well for Ware and their other backs, Charcandrick West and Knile Davis. Ware, who played for the Chiefs in training camp and the preseason, had been on their practice squad.
Most outlets say it's West who passed Davis on the depth chart as the team's RB2. Andy Reid went as far as saying West has a similar skill set to Charles while Davis is a one-cut runner. Davis has had success filling in for Charles in the past, but right now it seems like West is the back to own. However don't be surprised if Davis gets some work as well.
