An expansion team in 1976, the Seattle Seahawks had their typical expansion struggles, but as of this writing, they are one of the higher-profile teams in the National Football League.
Seattle was in the NFC in its inaugural year, only to switch to the NFC in 1977. This was the conference that they stayed in until 2002, and they would only win their AFC Division (West) twice, failing to win the conference. This would change when they moved back to the NFC, where they have represented the conference three times (2005, 2013 and 2014), and won the Super Bowl once (XLVIII)
With the Seahawks still under 50 years of age, this is a list that should see rankings change easily over the next few years.
This list is up to the end of the 2019 season.
Note: Football lists are based on an amalgamation of tenure, traditional statistics, advanced statistics, playoff statistics, and post-season accolades.
