INDIANAPOLIS (AP) Marlon Mack looks around the Indianapolis Colts locker room and sees the continually changing nameplates.
On Monday, Charcandrick West and Marquis Young went up on running back row. On Tuesday, James Williams joined the group. And more changes could be coming amid an injury rash that has decimated the Colts' backfield depth.
"You've just got to go out there and perform, each and every day," Mack said. "There's always competition and that's what they tell us, just go out there and perform at the highest level you can."
