The Chiefs also have Kolby Smith and third-round draft pick Jamaal Charles at running back and want to give considerable snaps to both players. Edwards said they also feel a need to get a look at Johnson.

"He needs to get out there because we’re running a new offense," Edwards said. "It kind of helps the running game and the whole team when he’s out there running the ball, and the guys in front of him blocking are going to be the guys doing it when the season starts."
