SEATTLE — Quietly, Aaron Donald, Jared Goff and the rest of the Los Angeles Rams seethed.
Less than two weeks earlier, they had watched as the Seattle Seahawks loudly celebrated a division title the Rams believed they gave away. Los Angeles desperately wanted another shot.
Behind a lot of Cam Akers churning yards on the ground and mostly a great defense, the Rams are moving on in the NFL playoffs at the expense of the Seahawks, whose NFC West crown was of little consolation after their 30-20 home loss in a wild-card playoff game Saturday.
"We come up here, and all week we were told how good they are and how we snuck into the playoffs," Goff said. "Two weeks ago you saw them smoking cigars and getting all excited about beating us and winning the division, and we were able to come up here and beat them."
Akers rushed for 131 yards and a touchdown, and Darious Williams returned his interception of Russell Wilson 42 yards for a score in the vengeance victory for Los Angeles.
"A lot of guys stepped up and answered the bell in a big way," Rams coach Sean McVay said. "Darious Williams showing up, I thought that was a huge momentum shift for us."
The best defense in the league during the regular season carried its dominance into the playoffs — even while missing unanimous All-Pro tackle Aaron Donald for much of the second half. No team was better at limiting yards or points than the Rams (11-6) during the regular season, and they continued to torment Wilson and the Seahawks (12-5).
Seattle's quarterback was under siege from the defensive front and a secondary that, minus one play, never let Tyler Lockett or DK Metcalf break loose. Donald, before leaving with a rib injury, and Jalen Ramsey were superb, but so were other role players such as Leonard Floyd, Jordan Fuller and Troy Reeder.
Floyd had two of the Rams' five sacks, two of the others belonged to Donald and the Rams allowed just 278 total yards and 11 first downs.
"We're excited about competing to go see who we play next and see if we can keep this thing rolling," McVay said. "But we'll enjoy this."
Williams' third interception against Wilson after picking him off twice in Los Angeles came as he jumped a wide receiver screen intended for Metcalf and returned it untouched for a 13-3 lead midway through the second quarter.
Akers added a 5-yard touchdown run just before halftime for a 20-10 lead. It proved enough against a Seattle offense disjointed and confused almost from the start.
Wilson had one of his worst playoff performances, finishing 11-of-27 passing for 174 yards. Wilson connected with Metcalf on a pair of scores, covering 51 yards in the first half off a broken play and 12 yards with 2:28 left to make the score more respectable.
Seattle never played with the lead and was 2-of-14 on third downs. Its first home playoff game in four years was a dud without its raucous home crowd, and the Seahawks' 10-game streak of home playoff wins is over.
Before Saturday, they hadn't lost at home in the postseason since January 2005 — also to the Rams, though before the team moved back to L.A. from St. Louis.
"I told these guys I have no place in my brain for this outcome," Seattle coach Pete Carroll said. "We were planning on winning and moving on."
The Rams pulled off the upset without a healthy quarterback for more then three quarters. John Wolford started for the second straight week but injured his neck when he dived headfirst in the first quarter and was hit in the helmet by Jamal Adams' shoulder. Wolford was taken to a hospital as a precaution, but McVay said he was in the locker room celebrating after the victory.
Said McVay: "I think it was really just a stinger. He definitely seemed good."
Goff took over less than two weeks after undergoing surgery on his right thumb that was injured in the Week 16 loss to Seattle. Goff didn't do anything spectacular but also avoided major mistakes as he was 9-of-19 for 155 yards. He capped the victory with a 15-yard touchdown pass to Robert Woods with 4:46 left after Seattle's D.J. Reed fumbled a punt.
Akers, the Rams' rookie ball carrier, was outstanding after not playing two weeks ago. Akers had the best rushing day by a Rams running back since Marshall Faulk went for 159 rushing yards against the Philadelphia Eagles in January 2002.
The Rams finished with 164 yards on the ground.
"He's made of the right junk. His heart, his passion for the game is special," Rams left tackle Andrew Whitworth said. "Anytime you see in this league that you can run the football in the playoffs, it's about more than just all the fantasy things you see in the regular season. It's going to be about imposing your will on another team."
