SEATTLE — If it wasn’t the end of an era — though it sure looked like it — it almost certainly was the end of a season.

True, two games remain and Seattle might still make the playoffs.

But the Seahawks simply looked old, slow and beat up Sunday as the younger, faster, healthy Rams blew past them for a shocking 42-7 dismantling at CenturyLink Field that likely handed the NFC West Division title to Los Angeles.

Seattle’s only hope to take the division now is to win its final two games at Dallas and at home against Arizona while the Rams lose at Tennessee and at home against the 49ers.

However, all that seems hard to fathom after what happened Sunday as the Rams did everything they wanted in all three phases in handing Seattle its worst defeat of the Pete Carroll era (the previous worst defeat was 41-7 against the Giants in Carroll’s first year in 2010) and worst of any kind since a 48-10 setback at Green Bay in 2009.

And while Seattle can still also make the playoffs as a wild-card team, the odds aren’t good — www.538.com determined Seattle had just a 16 percent chance of making it after the games of Sunday afternoon.

It was a game in which all that has happened to Seattle the past few months — season-ending injuries to standout defensive players Cliff Avril, Kam Chancellor and Richard Sherman — finally caught up to them, with their absences made worse because linebacker K.J. Wright sat out with a concussion and middle linebacker Bobby Wagner was visibly slowed with a hamstring injury.

All five are Pro Bowl players who had lifted Seattle to unforeseen heights, and Sunday mostly watched the team suffer a stunning low.

Wagner was listed as questionable but played after making it through a pregame workout.

And Wagner had one moment of glory — stuffing Todd Gurley on an third-and-one play in the second quarter.

But Wagner also appeared visibly slowed, notably when trying to chase down Gurley when Gurley scored on a 14-yard touchdown in the third quarter that made it 40-0.

He did not return after that play, with the outcome already having long been decided.

The Rams dominated in every phase from the first play of the game

The Rams outgained Seattle 238-59 in the first half, holding the Seahawks to just 2.2 yards per play and four first downs.

There was one brief glimpse of promise for Seattle when on the Seahawks’ third play of the game Wilson hit Tanner McEvoy over the middle for a first down. But after picking up 19 yards, McEvoy fumbled when hit by LaMarcus Joyner with Alec Ogletree recovering at the 40.

That led to a Rams’ field goal and a 3-0 lead that Los Angeles would never give up.

Seattle then went three and out and the Rams responded with another field goal.

Another Seattle three-and-out led to another punt and this time Los Angeles’ Pharoh Cooper returned the ball to the 1-yard-line, setting up an easy touchdown by Gurley that made it 13-0 at the end of the first quarter.

The Rams then appeared to give the Seahawks life, going for it on fourth and one at the Seattle 24 and somewhat oddly calling a roll out pass that was tipped by Bradley McDougald and picked off by Michael Wilhoite at the 13.

But any thought that sequence might give Seattle the break it needed to get back in the game — or maybe show that the Rams were still vulnerable — vanished quickly.

Seattle again went three and out and a Cooper 26-yard punt return gave Los Angeles the ball at the Seahawks’ 36.

From there the Rams needed just five plays to score, Gurley prancing in from 1-yard out, to make it 20-0.

Two plays into the next drive, Wilson tried to spin away from a hard rush from Robert Quinn and fumbled, with Los Angeles’ Morgan Fox finally falling on it at the Seattle 39.

The Rams needed just seven plays to score, this time on a 1-yard pass from Goff to Robert Woods to make it 27-0.

If that seemed surprising what happened next was just stunning.

After another Seattle three and out the Rams got the ball back at the Seahawks 47.

But after Frank Clark forced a fumble on second down the Rams appeared content to just run the clock out on third-and-20, handing the ball to Gurley.

Gurley, instead, broke through a huge hole and raced virtually untouched for a 57-yard touchdown, raising his hand in celebration before he got to the end zone.

It was just the second time since 1994 that a team had scored a touchdown on a run of third and 20 or longer.

It also made it 34-0 and made the second half a moot — and mute — point, with many fans deserting CenturyLink Field and giving the second half a preseason feel.

It was Seattle’s largest home deficit since trailing the Giants 41-0 in 2010.
