SEATTLE - For a while, it looked as if the Giants had found their missing heart. Then Marshawn Lynch ripped it right out of them.

The Seattle running back rushed for 140 yards and four touchdowns and quarterback Russell Wilson ran for 107 yards and a TD in the Seahawks' 38-17 win over the Giants Sunday at CenturyLink Field.

Although the final score was lopsided -- the third Giants loss of the season by at least 21 points -- it was tied at 17 late in the third quarter when Eli Manning lofted a deep pass for Odell Beckham Jr. in the end zone. That ball wound up intercepted by Earl Thomas after Beckham tipped it, and the Seahawks scored the next 21 points for the romp.

"It's hard to believe what you saw in the second half,'' Tom Coughlin said.

Giants cornerback Zack Bowman put it less eloquently but just as effectively when he said that the game turned "from sugar to [expletive]'' in the second half.

Seattle (6-3) ran for a franchise-record 350 yards, the third-most ever allowed by the Giants and the most since they gave up 366 to the Bills in 1978.

The Seahawks were the first NFL team to run for five touchdowns and at least 350 yards in a game since those 1978 Bills beat the Giants, 41-17.

For a team that takes its name from a type of bird, the Seahawks certainly did most of their damage on the ground. It wasn't so much the volume of the crowd noise in Seattle but the voluminous running that did in the Giants.

Yet it seemed as if this might be the game that pulled the Giants out of their skid and righted them for the season's second half. They were hanging with the defending Super Bowl champs, going ahead 14-7 and still holding a 17-14 lead at halftime. And they actually made a decent goal-line stand early in the third quarter to hold Seattle to a field goal for a 17-17 tie.

"There were times in the game where the game was nowhere near over,'' Beckham said, perhaps a bit naively.

But when it was finished, the Giants were saddled with their fourth straight loss, dropping their record to 3-6.

How bad is that? Last year, they started the season with a gut-wrenching six consecutive losses but won their next four games. In other words, a loss to the 49ers next week and this Giants season could, for the first time, be worse than 2013.

Now that's misery.

"We'll go one game at a time,'' Coughlin said.

The Giants trail the NFC East-leading Eagles (6-2) by four games in the loss column (the Eagles play Monday night against the Panthers) and the Cowboys (7-3) by three in the loss column.

"Everybody is going to be disappointed, everybody is going to be embarrassed, and rightfully so,'' Coughlin said. "But somehow, some way, we have to come back together once again because we have a very difficult opponent next week.''

The Giants actually made a few of the kinds of plays they'd been looking for, the "above the X's and O's'' type that Coughlin has practically begged for lately. They had three takeaways -- interceptions by Bowman and Quintin Demps and a fumble forced by Jameel McClain and recovered by Antrel Rolle. They also had Beckham making some terrific catches, including a 44-yarder on a deep pass from Manning in the first quarter. Manning's 6-yard touchdown pass to Preston Parker and Andre Williams' 3-yard TD run even gave them that 14-7 lead early in the second quarter.

But when the Giants had a chance to capitalize on Demps' pick early in the third quarter and were driving a bit, they were set back by Weston Richburg's holding penalty and had to punt.

"When you get interceptions and good field position against this team, you have to take advantage of that,'' Manning said. "To get no points off great field position is disappointing . . . We have to take advantage of the turnovers. They did and we didn't.''

The Seahawks did a lot of things that the Giants didn't, which is why they are the defending champs and the Giants are looking at a second straight season of woe.

"Everyone -- players, coaches -- we have to find an answer,'' Rolle said. "Because whatever we're doing, the answer is not there.''
