DE Cliff Avril, 2013-2017: Signed as a free agent in 2013, Avril, along with Bennett, was a key part of the Seahawks' ability to improve from really good on defense in 2012 to historically great in a Super Bowl winning season. In his first season with the Seahawks, Avril contributed 8.0 sacks and a team-leading six forced fumbles as part of a Seahawks defense that led the NFL in points allowed, takeaways, yards allowed and passing yards allowed. Avril continued to be a key part of the Seahawks defense over the next four seasons, finishing his five-year run in Seattle with 34.5 sacks, 14 forced fumbles and 88 quarterback hits, and he earned Pro-Bowl honors in 2016 when he had 11.5 sacks and five forced fumbles. Avril's career was unfortunately cut short, however, due to a neck injury early in the 2017 season. Avril was also the team's nominee for the Walter Payton NFL Man of the Year award in 2016.
DE Michael Bennett, 2013-2017: Bennett signed one day after Avril in free agency, and would spend the next five seasons establishing himself as one of the league's best and most versatile linemen. A three-time Pro-Bowler as a Seahawk, Bennett totaled 39.0 sacks, 69 tackles for loss, 118 quarterback this and seven forced fumbles in his time in Seattle, and he led the Super Bowl winning 2013 team with 8.5 sacks. Bennett also had one of the biggest personalities in team history, which sometimes came through in his sense of humor, and sometimes came through in his passion for social justice issues. Bennett, who was named the team's nominee for the Walter Payton NFL Man of the Year Award in 2017, joined forces in retirement with Avril and Doug Baldwin to form Champions of Change.
DE Jeff Bryant, 1982-1993: A first-round pick in 1982, Bryant spent his entire 12-year NFL career with the Seahawks, starting 167 games and appearing in 175, totals that rank fifth and sixth in franchise history, respectively. Bryant, who ranks third in Seahawks history with 63 sacks, also finished his career ranked in the top 10 in tackles, forced fumbles and fumble recoveries, blocked field goals and blocked extra points. Bryant, the co-winner of the 1992 Steve Largent Award along with Nash, had his best season as part of the standout 1984 defense, recording 14.5 sacks, two fumble recoveries and an interception for a unit that also featured Defensive Player of the Year Kenny Easley and Pro-Bowl seasons from Easley, Nash and Dave Brown, and that forced 63 turnovers, the most by an NFL team since the merger.
DE Jacob Green, 1980-1991: Green joined the Seahawks as the 10th overall pick in the 1980 draft, and over the course of the next 12 seasons, he would go on to establish himself as one of the top players in franchise history. A member of the Seahawks Ring of Honor, he is the franchise's all-time leader in sacks with 115.5. Green was a two-time Pro-Bowl selection who started 176 of 178 games played over 12 seasons in Seattle, giving him the third most starts in franchise history behind Hall of Famers Steve Largent (197) and Walter Jones (180), and the fifth most games played. Green's 28 forced fumbles and 17 fumble recoveries are also franchise records, his 718 tackles rank seventh, and second among defensive linemen, and his four return touchdowns (two interception returns and two fumble returns) are tied for second most. Green is also one of five players in team history with four sacks in a game.
