Clinton Portis IS a system back...

[MTK]

Wilbon says it all right here:

They're alive and feeling good about their old-fashioned approach to the game, built around defense, an increasingly punishing offensive line and Clinton Portis. I don't want to hear any more about Portis making too much money, or Portis costing the Redskins too much in the trade with Denver, or Portis's midweek costumes not being funny. When a player runs for 100 yards or more four straight games, when he sticks your chin out and makes the tough runs against the Cowboys and Giants with the season on the line, he can wear a pair of four-inch Jimmy Choo pumps and an evening gown to practice on Thursday.
