"You just want to see that steady No. 2 running back right now that can come in in a pinch or come in and give Jamaal some needed rest, and has that explosiveness," Chiefs offensive coordinator Doug Pederson said. "He's more of your downhill type of runner."
HC Andy Reid has always rode his RB1 since his days with the Eagles so it will be interesting to see if they try to limit Charles' workload in games. One thing is for sure, Davis makes a great handcuff for Charles owners and has proven that he can carry the load. He's getting a lot of reps in camp so far.
