In 1983, the Seahawks hired former LA Rams coach Chuck Knox as head coach. Finishing with a 9–7 record, the Seahawks made their first post-season appearance, defeating the Denver Broncos in the Wild Card Round, and then the Miami Dolphins, before losing in the AFC Championship to the eventual Super Bowl champion Los Angeles Raiders. The following season, the Seahawks had their best season to that point, finishing 12–4; it would remain the best win–loss record in franchise history until their 2005 season.

In 1988, Ken Behring and partner Ken Hofmann purchased the team for a reported $80 million. The Seahawks won their first division title in 1988, but would miss the playoffs for the following three seasons, after which Knox left the team.
For most of the 1990s, the Seahawks continued to struggle. They saw three consecutive losing seasons (1992–1994) under head coach Tom Flores, including a franchise worst 2–14 season in 1992. Following the 1994 season, Flores was fired from the team and Dennis Erickson was brought in as head coach.
