The Seattle Seahawks secured one of the most important pieces of their defense. Leonard Williams signed a three-year, $90 million contract extension that includes $56 million guaranteed, according to ESPN and NFL Network reports.
The new deal keeps the defensive tackle with the defending Super Bowl champions and represents another major move by Seattle to retain the players who were central to its championship. Williams becomes the third high-profile Seahawks player to receive a significant extension during 2026. :contentReference[oaicite:5]{index=5}
How much will Leonard Williams make with the Seahawks?
The contract is worth $90 million over three years, with $56 million guaranteed. The deal ties Williams with Vita Vea for the fifth-highest average annual salary among NFL defensive tackles.
Only Jalen Carter, Quinnen Williams, Jeffery Simmons and Chris Jones rank ahead of them, highlighting the level of recognition Seattle is giving the veteran defensive lineman. :contentReference[oaicite:6]{index=6}
Williams was entering the final year of the three-year, $64.5 million contract he signed with Seattle in March 2024. The new agreement prevents the team from potentially losing him in free agency in 2027.
Leonard Williams was key to Seattle's Super Bowl run
Seattle's decision is easy to understand considering Williams' production. The 32-year-old was a key part of a defense that finished as the NFL's top scoring defense during the 2025 season.
He recorded seven sacks during the 2025 regular season and added another sack in the playoffs, when the Seahawks went on to win Super Bowl LX.
Williams was also named second-team All-Pro in 2025 and earned his third Pro Bowl selection. He has made the Pro Bowl in both of his full seasons with Seattle. :contentReference[oaicite:7]{index=7}
A player Seattle considers foundational
Head coach Mike Macdonald described Williams as a foundational player for the organization and praised both his production on the field and his impact as a teammate.
The extension is part of a broader Seahawks strategy to retain players they consider pillars of the organization. In March, Seattle made Jaxon Smith-Njigba the NFL's highest-paid receiver with a four-year, $168.6 million extension.
Earlier this month, the team made Devon Witherspoon the league's highest-paid cornerback with a four-year, $132 million contract. In June, Seattle also extended outside linebacker Derick Hall for three years and $42 million. :contentReference[oaicite:8]{index=8}
What does Leonard Williams bring to the defense?
Williams combines size, experience and the ability to generate pressure from the interior of the defensive line. Over 11 seasons, he has recorded 61.5 sacks in 175 regular-season games.
His best individual production came in 2020, when he recorded 11.5 sacks with the New York Giants. His time in Seattle, however, has been particularly productive.
In 2024, he recorded 11 sacks and also returned an interception 92 yards for a touchdown, the longest pick-six by a defensive lineman in NFL history, according to ESPN Research. :contentReference[oaicite:9]{index=9}
Seattle is betting on defensive continuity
Williams' extension is even more important because the Seahawks will attempt to defend their championship in 2026. Maintaining continuity on a defense that played a major role in the Super Bowl is an obvious priority.
Seattle is choosing to keep a core of players who know Macdonald's system and have already proven they can compete at the highest level.
Williams has also said that his time in Seattle transformed his career and that he is excited about potentially finishing his career with the organization. After winning a Super Bowl with the Seahawks, he now has long-term contractual stability as one of the leaders of the defense.
For Seattle, the message is clear: after building a championship team, the priority is keeping a core capable of competing again. Leonard Williams' extension is another indication that the Seahawks are not willing to dismantle the defense that took them to the top of the NFL.
