SEATTLE — Running back Marshawn Lynch and the Seattle Seahawks have waited more than a month to get their offensive line in order, and on Sunday afternoon they showed why it mattered.

Lynch rushed for a season-high 140 yards and four touchdowns as the Seahawks piled up a franchise-record 350 yards on the ground while pulling away for a 38-17 win over the New York Giants.

Playing behind an offensive line that saw the return of Pro Bowlers Max Unger and Russell Okung from injury, Lynch ran 21 times for his highest rushing total since Week 11 of the 2013 season, while Seattle quarterback Russell Wilson added 107 rushing yards and a touchdown.

“Any time you’ve got those two guys in there, that’s a big help,” offensive lineman J.R. Sweezy said of getting Unger and Okung back. “They’re two Pro Bowlers, so obviously that’s big.”

Two of Lynch’s touchdowns came in the pivotal fourth quarter as the Seahawks (6-3) rallied back from a 17-14 halftime deficit. He gave Seattle a 24-17 lead on a 3-yard touchdown run two minutes into the fourth quarter, then he added another score on a 17-yard run five minutes later to put the game away.

“Marshawn was just extraordinary today,” Seahawks coach Pete Carroll said.

The previous team record for rushing yards in a game was 320, set in a 2005 win over the Houston Texans.

Seattle had 200 rushing yards after halftime, outscoring the Giants 24-0 along the way.

“It’s hard to believe what you saw in the second half,” New York coach Tom Coughlin said.

What the Giants said:

“It was kind of how our whole season has been. You can see the spurts you know you can play well, and sometimes you just don’t — and that is the frustrating thing about it. It’s hard. Just have to keep battling.” – Cornerback Dominique Rodgers-Cromartie

“We have seven games left. Anything can happen.” – Defensive end Jason Pierre-Paul

“I’m sure ill-advised would be the phrase you could use.” — Coach Tom Coughlin, on Eli Manning’s tide-turning interception late in the third quarter

What the Seahawks said:

“I think we started out of character early, with not staying on top, but we made the correct adjustments and got everything together. It’s all about strategy and understanding how they want to attack you, but they did some things we haven’t seen.” — S Earl Thomas

“We had two bad plays. Other than that, we played a great football game.” — QB Russell Wilson

“Obviously, we’re very grateful, but we’re looking forward to the next week already. Looking forward to playing a good Kansas City team and hopefully taking some of this game with us.” – Left tackle Russell Okung

What we learned about the Giants:

1. The Giants’ run defense leaves a lot to be desired. New York allowed Seattle to pile up a Seahawks franchise-record 350 rushing yards on Sunday, and a lot of it came because of missed tackles. The Giants got fooled by QB Russell Wilson’s read-option plays to the outside all afternoon long, then Seattle RB Marshawn Lynch pounded through would-be tacklers over the entire second half. In the end, the Seahawks scored five rushing touchdowns in New York’s 38-17 loss.

2. They’re not big on close games. In what finally looked like a down-to-the-final minute game, the Giants found themselves getting blown out in the fourth quarter Sunday. The 38-17 loss to Seattle marked the sixth time in six losses this season that New York has been outscored by double digits. By contrast, the Giants have posted victories by margins of 10, 13 and 31 points.

–QB Eli Manning had a solid first half on Sunday, but things got away from him after halftime as the Giants saw a three-point halftime lead turn into a 38-17 loss in Seattle. Manning was 16 for 23 for 192 yards and a touchdown while leading the Giants to a 17-14 lead at the half; over the final two quarters, he went 13 of 21 for 91 yards and an interception. Manning also gave up a fumble when he lost the ball as he went into his throwing motion in the fourth quarter.

–WR Odell Beckham Jr. had a breakout first half Sunday, finishing the game with seven receptions for 108 yards. New York’s first-round pick was the Giants’ most effective target Sunday, with five receptions and 92 yards by halftime.

–CB Zack Bowman made his second start of the season, replacing injured Prince Amukamara, and had a first-half interception. Bowman provided solid coverage on a day when pass defense was the least of the Giants’ problems.

What we learned about the Seahawks:

1. RB Marshawn Lynch sure likes having his offensive line back. On a day when the Seahawks welcomed back Pro Bowl linemen Max Unger and Russell Okung from injury, Lynch broke out for a season-best 140 rushing yards. A lot of his success came from QB Russell Wilson (107 rushing yards) gashing the New York defense early in the game, as Seattle piled up a franchise-record 350 yards on the ground.

2. They’re good enough to survive turnovers. On a not-so-rare day that saw rain in Seattle, the Seahawks had a rare day in that they couldn’t hang on to the ball. Two interceptions and three fumbles were less costly than they could have been – resulting in only a single Giants touchdown. Seattle recovered two of the fumbles – in a span of three plays during a drive that resulting in the clinching touchdown – and only one of the interceptions proved costly.

–C Max Unger (strained foot) returned to the lineup and gave a big boost to the Seattle running game. The Seahawks piled up a franchise-record 350 rushing yards in the win. Unger had missed four games with the injury.

–RB Marshawn Lynch ran for a season-high 140 yards and four touchdowns in Sunday’s 38-17 win over the Giants. It was Lynch’s most productive outing of the season, and it’s no coincidence that the performance came on a day that the Seahawks got LT Russell Okung and C Max Unger back from injury.

–DT Brandon Mebane left Sunday’s game with a strained hamstring in the first half. Coach Pete Carroll said after the game that he did not yet know the severity of the injury. Mebane has been an anchor on Seattle’s defense this season.
