Coming into Sunday's game, the Kansas City Chiefs were putting up offensive numbers that, for the better part of a decade, folks have come to expect from an Andy Reid-coached, Patrick Mahomes-quarterbacked team.

Through five games, all of them victories, the Chiefs were averaging a league-best 414.0 yards per game, scoring 28 points per game (fifth) and rushing for 159.8 yards per game (second) with Kenneth Walker III leading the NFL in rushing.

But for as good as the Chiefs offense has been, the Seahawks defense was far better on Sunday, holding Kansas City to a single field goal in a dominant 20-3 victory at Lumen Field.

"We can play," middle linebacker Ernest Jones IV said. "We go out there, and that's our goal, shut you down, shut your lights out. That's big ups to the defense today. We came out there and executed. We were able to go out there and stop a real good offense."

And "shut your lights out" was a pretty apt description for what Seattle's defense did to Mahomes, Walker and company over the course of four quarters and eight Chiefs possessions. In addition to being held to a single field goal, matching the lowest output for the Chiefs with Mahomes as a starter, Kansas City was also limited to just 11 first downs and 213 yards, both of which are franchise lows with Mahomes at the helm. It was also the first time in Mahomes' career that his offense failed to reach the red zone in a game.

"Our guys played great, man," Seahawks coach Mike Macdonald said. "They're just a bunch of warriors. We had some guys that were banged up that played through some things that went in the game. You watch really the effort of our football team, really over the last few weeks the effort that they've played with, the physicality, going into a short week playing the way they did against Denver, then coming back and putting themselves in a position to play the way they did today. How do you not just tip your cap to those guys. We love our group. We have a great group. I think to a man, if you ask them, they're proud of the effort, but they know we can be better. I put us in a couple of tough spots that they bailed me out of. That's 12 as One. That was pretty cool."

Seahawks receiver Jaxon Smith-Njigba, who had another big game with 150 yards and a touchdown on nine catches, but was more animated after the game when talking about his team's defense.

"Super incredible," Smith-Njigba said. "Time after time again, I continue to say it, they're the best in the world and they prove it, they back it up, with the swagger and how fast they're playing is incredible. We got some great guys. We know they're going to come in each week and do their thing."

The Seahawks' pass defense was great, holding Mahomes to just 165 yards on 33 attempts while intercepting him once, with Ty Okada picking off a pass that was off target because of pressure and a hit from Nick Emmanwori. But what really keyed the defense's dominance was the way it played the run, holding Walker to just 36 yards on 14 carries, giving him a 2.6-yard per-carry average. It was the 36th straight game, postseason included, that the Seahawks have not allowed an individual 100-yard rusher, and that streak continued against a player who had rushed for a league-high 665 yards through five games while averaging a league-best 6.3 yards per carry.

"We have to play in waves," Macdonald said. "He's still going to break tackles. I'm sure he broke a host of tackles. That's what he does. So we had to get people to the football. That gave us the best chance. I felt the guys played like that. I felt we played great team defense today."

Said cornerback Devon Witherspoon: "We stopped the run really well, we played tougher across the board, and we played great complementary football today.

"It takes all 11 of us, really 12 including our fans. We all get to the ball, we swarm, we play relentless. We play a style that you don't want to play, bro, and I think we put that on tape."
