Portis finished his career second on Washington’s all-time rushing list. He fell 648 yards shy of John Riggins’ franchise record of 7,472 rushing yards.

In addition to his rushing skills, Portis was highly respected by Redskins players and coaches for his skills as a pass protector, and widely known by fans as a locker room character.
