The Seahawks and Tampa Bay Buccaneers were the two expansion teams that began playing in the 1976 season.

The original Seahawks team had some notable players including future Hall-of-Fame receiver Steve Largent, linebacker Mike Curtis who had helped the Colts win a Super Bowl, and Al Cowlings, who became world famous in 1994 for being O.J. Simpson's driver during the surreal freeway chase. Coach Jack Patera was the brother of Olympic weightlifter and pro wrestling star Ken Patera.

The Seahawks won AFC West titles 1988 and 1999. The team moved to the NFC West in 2002. Since then, the Seahawks have been to three Super Bowls, including a 43-8 romp over the Denver Broncos in 2014. Seattle has also won six NFC West titles since 2004.
