Since Seahawks head coach Pete Carroll and general manager John Schneider teamed up, Seattle has been one of the premier franchises in the NFL. They’ve been to two Super Bowl since 2010, winning one in dominant fashion. They’ve also found a way to maximize the talent of players some teams have overlooked or simply given up on.

While Seattle’s 2016 season didn’t end with a victory parade through the streets of downtown, 2017 is shaping up nicely. The Seahawks have one of the easiest strength of schedules in the league, and they will hopefully have a healthy Earl Thomas and Tyler Lockett back and ready to go.

But Seattle will be looking to make improvements between now and then via the draft and free agency. With that in mind, here’s a look at the three best free agent signings of the Pete Carroll era.

Michael Bennett

There’s no denying that Bennett is one of the best defenders in the game today, and one of the big reasons Seattle has been so dominant up front. He can rush the quarterback, stuff running backs at the line and disrupt a team’s offensive flow with just his presence alone. But Bennett wasn’t always viewed as a top-tier defender. After the Tampa Bay Buccaneers chose not to bring Bennett back after the 2012 season, the defensive end signed with the Seahawks for one-year and $5 million. In his first season in the Emerald City, Bennett recorded 8.5 sacks as the Seahawks went on to win Super Bowl XLVIII over the Denver Broncos. Bennett was quickly locked up to a four-year $28.5 million contract following the Super Bowl win. It’s been a win-win for both sides.

Cliff Avril

Like Bennett, Avril joined the Seahawks prior to the start of the 2013 season. Avril spent the first five years of his career with the Detroit Lions, and signed with Seattle on a two-year $13 million contract. Avril has been an anchor for the Seahawks defense every since, and this past season recorded a career-high in sacks with 11.5. It was his most sacks since he had 11.0 in 2011 with Detroit.

Michael Robinson

Sure, Robinson may not be the first name that jumps out at you when talking about big free agent signings for the Seahawks, but his presence on the field coupled with his rapport with fans made him an instant favorite in Seattle. Robinson joined the Seahawks in 2010, Carroll’s first season with team, and retired after Seattle’s Super Bowl XLVIII win. His ability as a blocker helped paved the way for Marshawn Lynch to be one of the league’s most dominant running backs, and to this day the two still maintain a close friendship.
