The Seattle Seahawks joined the National Football League (NFL) in 1976. The team went through seven seasons in the league before making its first postseason appearance in 1983, defeating the Denver Broncos in a wild-card game and upsetting the Miami Dolphins before losing to the Los Angeles Raiders 30-14. Seattle returned to the postseason in 1984, 1987, and 1988 before enduring a 10-year playoff drought. After losing a wild-card game to the Dolphins in 2000, the franchise missed out on postseason play three years in a row.
Beginning in 2003, Seattle became a more consistent presence in the postseason. The team made five consecutive playoff runs between 2003 and 2007, including trip to the Super Bowl in 2005. Facing the Pittsburgh Steelers, Seattle scored first and trailed the Steelers by just four points midway through the fourth quarter, but ultimately fell 21-10.
Seattle returned to the Super Bowl in 2012 to record one of the most lopsided victories in NFL history. Touted as a match up between defense and offense, the defensive-minded Seahawks scored 36 consecutive points before the Denver Broncos finally scored a touchdown to close the third quarter. It was Denver’s only score, and the Seahawks won the game 43-8. Seattle returned to the Super Bowl the following season but could not repeat, dropping a tight contest to the New England Patriots.
