Portis doesn't do 'limited fashion'

Posted by ESPN.com's Matt Mosley

Redskins coach Jim Zorn said he might be willing to play running back Clinton Portis (knee) "in a limited fashion" Sunday, but I have a hard time believing that. If Portis says he can go -- which seems like a stretch -- he'll start and carry the ball at least 18 times.

He's been in this type of situation several times before. When Portis takes the field, there's no such thing as "limited fashion." Portis is not a change-of-pace back. He needs carries to bang away at a defense. He's also one of the best pass-blocking backs. If he's active, he won't allow Zorn to ease him into the flow.

If he plays, he'll have 20 carries and 100 yards. If he's not able to go, the Redskins could struggle mightily in the running game.
