Marshawn Lynch keys Seattle offense

Marshawn Lynch has surpassed the 100-yard mark just once in the past 10 games, but he remains the epicenter of Seattle’s offense.

Let him run wild, and the Cowboys have no chance. Dallas ranks 20th in the NFL in run defense, allowing 122.0 yards per game.

Arian Foster ran through the Cowboys for 157 yards on 23 carries last week. The Cowboys will have middle linebacker Rolando McClain available to help stop Lynch.

McClain aggravated his strained groin late in the fourth quarter against Houston and missed overtime, but he practiced Friday and is expected to play.

If McClain's playing time is limited, the Cowboys will probably use rookie middle linebacker Anthony Hitchens at middle linebacker when he needs a break.

“He’s a great player. He’s a dominant running back who, in many ways, establishes the identity of their team,” coach Jason Garrett said. “He’s physical, he’s downhill, he's really hard to tackle, and he plays with a relentless spirit to him.

“I think he’s under-appreciated as a receiver and as an athlete. He has great change of direction and body control and great hands. He makes a ton of plays and shows up for them every week.”

Lynch has caught eight passes for 85 yards in the past two games. His 30-yard catch-and-run last week helped clinch the Seahawks’ win over Washington.
