In the first quarter it was an Ernest Jones IV forced fumble, with a Julian Love recovery. In the third quarter, it was an Jones IV interception. And in the fourth quarter it was a DeMarcus Lawrence forced fumble that was recovered by Nick Emmanwori.

Lawrence on his forced fumble said, "I ain't running for nothing. You feel me? So if imma run, I'm going to try to make sure I take the ball from you."

And he was successful in just that, forcing two fumbles on the night.

But it was Jones IV who was at the middle of the performance put on by Seattle's defense, and finished the game with six tackles, an interception, a pass defensed and a forced fumble.

Jones IV, often described as the quarterback of the defense, made two plays that were energy shifting. Jones missed practice on Wednesday and was limited on Thursday with an illness.

"It was great," Mike Macdonald said. "Look, this guy was not in a good spot on Football Thursday (Wednesday). So for him to kind of get up to speed, get ready to play. The guys follow his lead. Two tremendous plays to really change the course of the game with those takeaways."

Lawrence said, "E.J., he is our captain, man. He hold us together, he makes sure all of us are in the right place, and he's a dawg and he gets the ball for us. Shout out to E.J., man, let's keep it going."

The Seahawks defense as a whole, which has been the story all season long, was once again dominant in Seattle's 41-6 win. Seattle forced three turnovers, scoring on two of them and held the 49ers out of the endzone for the second straight game.

"That's big, honestly" Jones IV said. "That's the style we want to play. That's complimentary football. Getting turnovers on defense, that's something we strive to do. And when the offense is able to capitalize and get touchdowns out of that, builds our confidence and we just want to go get the ball more now and give them more opportunities to just go get as many points as we can."

For the offense, who was able to capitalize off of the success of the defense on Saturday night, receiver Cooper Kupp said, "It's unreal the way those guys are playing right now. The camaraderie that they have, the violence that they play like, it's fun to watch. It's fun to see it happen during the week and their preparation, the way they play off each other and communicate with each other, the loose and focused nature of practice. When they're on the field, they are locked in. They're talking to each other and making sure they're doing things the right way. Not just, do what the coach says, but do what the coach says and understand what the offense is doing and how they can make things better. Then when they're on the sidelines, they're just enjoying being around each other. It's a really close group over there, and it's a ton of fun to see them do what they do each week."

This is the fourth time that Kyle Shanahan's offense, through 163 games, has been held to 7 points or less.

All game the defense did not let up. Along with the three forced turnovers, Seattle also forced a turnover on downs when the 49ers attempted three fourth-down conversions. The 49ers were able to convert only six of 12 third downs. And the defense also made life difficult for quarterback Brock Purdy all night, with five quarterback hits, 13 pressures and one sack.

49ers center Jake Brendel said, "I think this defensive front is one of the best in the league at bringing pressure. They are a very selfless group, and they rush very selflessly. One guy might pick a guy for the guy next to him to get open. You don't see that across the league, you see a lot of more selfish groups. They executed on third downs, and second-and-long. I feel like if we were more productive on first and second downs, we wouldn't be in those situations."

At the podium postgame, Lawrence was rocking a chain that had M.O.B. on it, that stands for Seattle's mantra, "mission over bull(expletive).

"Just letting the world know how we coming," Lawrence said about the chain, and as a result of that slogan, Seattle's defense is reaping the benefits.

Lawrence said keeping the 49ers out of the end zone was, "just a testament to all the work that we've been putting in all year. We understand what we have here, just playing complimentary football and let the rest take care of itself."

Adding, "It's commitment and dedication to our brotherhood and where we want to go. I feel like we have a room mix of young guys and older guys. And once you bring our talents and our efforts together, we have a complete puzzle."

Leonard Williams, who had the one sack on Purdy, a tackle for loss and two quarterback hits, met with the media after the game and was sporting a black Louis Vuitton cardigan and was carrying a briefcase that he said was holding the "Dark side game plan." And while he was joking, this Seahawks defense has figured out the winning formula and has shown that they have their game plan down pat.

"This defense is amazing," Williams said. "It's fun to play with them. Mike has this slogan loose and focused that he's been instilling in this team since day one he got here. And I think that's really what has allowed this team to play so free, play so fast. And I think we just believe in one another. We trust in one another. And regardless of where we're at on the field, when we take the field, I think we trust in ourselves. We trust in the guy next to us and we get the job done and it's amazing to not let them score."
