ASHBURN, Va. (January 7, 2012) -- Pete Carroll says the "field" in FedEx Field is "horrible."

Mike Shanahan doesn't go that far, but he agrees the grass isn't always greener at the Washington Redskins stadium.

The playing surface was a mess when the Redskins hosted the Seattle Seahawks in the NFC wild card playoffs. There were plenty of bare sports, and dirt was flying with many of the steps taken between the hash marks. Washington quarterback Robert Griffin III and Seattle defensive end Chris Clemons left the game with knee injuries.

Seahawks coach Carroll told 710 ESPN Seattle on Monday that it was "as bad as a field can get" considering the weather was dry.

Redskins coach Shanahan says he'll address the issue before next season. He says he'd consider a switch to an artificial surface.
