SEATTLE – The task was obvious, but not simple: Contain Seattle's running game, led by Marshawn Lynch, and then tee off on quarterback Tarvaris Jackson and the passing game.

The Eagles defense couldn't get it done on a long, frustrating, fruitless Thursday night.

Lynch, who entered the game with three 100-plus-yard games in the previous four games, added another huge performance against the struggling Philadelphia defense. Lynch ran for 148 yards on 22 carries, including scoring runs of 15 yards and 40 yards and his bruising style left Eagles defenders scattered all over the field. Seattle pushed the defense all over the field, gaining 174 yards on 33 rushing attempts.

"We knew what they were going to do. Marshawn breaks a lot of tackles and runs hard," said middle linebacker Jamar Chaney. "We didn't do a good job on him. We just didn't get the job done."

If this game was a challenge to the defense's ability to stop the run against a team that relies so heavily upon that phase of the game, the Eagles did not pass. On Lynch's first scoring run, he emerged from a gang of defenders and plowed his way into the end zone to give Seattle a 7-0 lead.

"I wasn't even sure who had the ball," said defensive end Trent Cole. "He was in that pile and I thought he was down and then all of a sudden he was running for the end zone."

Then Lynch took a handoff to the right side later in the first half and burst through a hole on the left side of the Eagles defense, got to the sideline and outran the defense into the end zone to make it 14-0.

"I don't even think he was touched," said Chaney. "He got through the hole and got to the sideline and it was wide open from there."

At times the Eagles did a nice job bottling up Lynch, but when the Seahawks needed him, Lynch delivered with his punishing style.

Seattle converted 5 of 12 third downs and gave Tarvaris Jackson plenty of opportunities to make plays. He completed 13 of 16 passes for 190 yards and compiled a passer rating of 137. The defense failed to produce a takeaway.
