Bennett signed with the Seahawks in 2013 one day after fellow defensive lineman Cliff Avril, making for one of the most significant two-day stretches of the offseason in franchise history. Bennett, along with Avril, was a key addition to an already great defense who helped the Seahawks get over the hump in 2013 and win the first Super Bowl in franchise history. Between delivering some of the more memorable quotes, and sack celebrations, in team history, Bennett was a three-time Pro-Bowl selection in Seattle, recording 39 sacks, 69 tackles for loss and 118 quarterback hits in five seasons. Bennett also made, and continues in retirement to make, a big difference in the community, not just in the Seattle area but also his hometown of Houston and in Honolulu where he and his family reside.  

An outspoken voice for social justice and a leader on the field and in the community, Bennett was named the team’s nominee for the Walter Payton NFL Man of the Year Award in 2017, and in retirement he joined forces with Avril and Doug Baldwin to form Champions of Change.
