The Seahawks’ defensive front played a big role in the team winning the Super Bowl last season, and that group should again lead the way in 2026.

With Seahawks training camp kicking off later this month, Seahawks.com is counting down, in no particular order, 10 of the most intriguing storylines, position battles and players heading into the 2026 season. So far, we've looked at at special teams, and the return game in particular, safety, cornerback and off-ball linebacker, and today we turn our attention to the defensive front. Check back Monday when we look at the offensive line.

Key Defensive Line/Outside Linebacker Additions: Dante Fowler Jr. (free agent signing), Deven Eastern (seventh-round pick).

Key Defensive Line/Outside Linebacker Departures: Boye Mafe (signed with Bengals).

The Seahawks rolled to a dominant victory in Super Bowl LX for a number of reasons, including standout play in all three phases, great coaching and a great scheme, and the closeness of the team that was, to borrow one of head coach Mike Macdonald's favorite phrases, the team's secret sauce all season long.

But one of the keys to that 29-13 victory was one of the things that made the Seahawks so good all season long—their defensive front was dominant. The Seahawks recorded six sacks in the Super Bowl, two of which produced turnovers, and aside from a few Drake Maye scrambles, the Patriots didn't get anything going on the ground as well, with their running backs combining for 42 rushing yards on 13 carries.

That lines up with what the Seahawks were able to do all season. Not only did a great front and Macdonald's scheme produce a formidable pass rush—the Seahawks' 47 regular season sacks were tied for seventh most in the league—they were also nearly impossible to run against despite playing nickel and dime packages at some of the highest rates in the NFL. Even though the Seahawks regularly played with light boxes, they held opponents to a league-low 3.7 yards-per-carry average, allowed the third fewest rushing yards, the second fewest rushing touchdowns (9), the second fewest rushing first downs (83), and were tied for the fewest 20-plus yard runs allowed with five.

To be sure, players on all three levels of the defense contributed both to the pass rush and the run defense, but it all starts with a dominant defensive front led by the likes of linemen Leonard Williams, Byron Murphy II and Jarran Reed, and outside linebackers DeMarcus Lawrence, Uchenna Nwosu and Derick Hall.

And the great news for the Seahawks in 2026 is that all of the players listed above are back in 2026, with the only notable departure from that 2025 front being that of Boye Mafe, who signed with the Bengals in free agency.

With Mafe leaving, the Seahawks signed veteran outside linebacker Donte Fowler Jr., adding a player who has 58.5 sacks in his 10-year career as well as a proven track record as a strong run stopper. The Seahawks are also expecting more out of interior lineman Rylie Mills, who missed most of his rookie season but came on strong late, punctuated by a dominant sack in the Super Bowl, and could get more contributions out of young edge players like Connor O'Toole, Jared Ivey and Jamie Sheriff. There's also a lot of depth in players like Mike Morris, Brandon Pili and rookie Deven Eastern.

An in addition to having a lot of talent and depth, the Seahawks are also relying on continued growth heading into their third season in Macdonald's scheme.

"We have been learning each other for the last two years," Williams said. "Going on Mike's third year here, people should have more of a grasp of the way he calls defenses, what type of defenses he's calling in certain situations, allowing us to play ahead of the snap pretty much. The more we diagnose the defense and get used to all those moving pieces and changes, that's just going to allow us to play that much faster."

And, as Williams noted, the continuity should help as well.

"That's a huge piece of it," he said. "When I can trust the guy next to me, know the guys next to me, we play on a different tempo, we sometimes can just look at each other and know how we're going to rush up front, how we're going to play blocks. That continuity is just huge. We just talked about how guys come and go and stuff like that. I think we've done a good job here of keeping the majority of the same guys around each other. That allows for culture to grow, in my opinion."
