RENTON, Wash. - The Seattle Seahawks were more than familiar with the face of the Washington Redskins' franchise. After all, Robert Griffin III can be seen nearly any time of day on television hawking cars or sports drinks or athletic gear. Preparing for Sunday's wild-card showdown at FedEx Field, the Seahawks have spent the past several days in the film room trying to familiarize themselves with the arm and legs of the Washington Redskins' talented rookie quarterback, too.

The conclusion?

"He has all of those commercials for a reason," Seattle Coach Pete Carroll said.

There is no sure-fire blueprint yet, no defensive recipe that might neutralize both Griffin's passing, and running abilities. Seattle's defensive coordinator, Gus Bradley, has been studying film and he learned quickly what every other defensive coach who has faced the Redskins this season picked up on: It could be a no-win situation. Defenses can't give Griffin too much time in the pocket, but they also can't allow Griffin to scramble around the end.

The Seahawks, which gave up the fewest points in the NFL this season (15.3 per game), have encountered similar foes this season and have found some success defending the read-option.

The most mobile quarterback the Seahawks have faced this season was Carolina's Cam Newton in October. Seattle won the game 16-12 and forced Newton into perhaps his most ineffective outing of the year. Newton finished 12 of 29 passing for 141 yards. Newton was the Panthers' leading rusher, but he carried the ball just seven times for 42 yards, losing a fumble.

The Seahawks also faced San Francisco and Colin Kaepernick on Dec. 23, beating the 49ers 42-13. Kaepernick's passer rating of 72.0 was the worst of his seven starts this season.

Of the 31 NFL passers with at least 270 pass attempts this season, Griffin has thrown the fewest interceptions (5).
