They run the ball as well as anybody in the league."The Panthers rank 24th in the NFL in run offense, averaging 93,8 yards per game.Injuries have hurt Carolina. DeAngelo Williams was placed on injured reserve after six games with a foot injury. Jonathan Stewart missed last Sunday's game with a concussion.Mike Goodson filled in Sunday and gained 100 yards on 23 carries."All of their [running backs] can play," Harbaugh said. "So, the run game is going to be the bottom line."
