1984 - Won Wild Card (Raiders), Lost Divisional (Dolphins)
2014 - Lost Super Bowl
2020 - ???
Only finishes better than 12-4 were the 13-3 years (2005, 2013) which resulted in 2 Super Bowls with 1 win.
3 of 4 prior finishes of 12-4 or better have seen the Seahawks in the Super Bowl.
Top 5 season in the history of the franchise, yet there are still many people here that aren't satisfied.
Enjoy it! Once PC is gone it'll be a long time before we have a team that is consistently in the running for the Bowl.
