This is already one of the legendary teams of the past decade.
That in itself should be payback for years of losing.
This team played incredible football against almost every team they faced. I remember being very worried about the Carolina game, and it turned out that Carolina was a pretty damned good team. But the defense on this team got better and better, it was a like a room where the walls were squeezing closer. By the end of the year going against the defense was like being thrown into a dark closet, a closet filled with rusty barbed wire and angry snakes. And a guy with a sledgehammer that wants to smash people in the ribs.
10 years from now, if people are still playing video games, you will probably be able to dial up the 2013 Seahawks as one of the All Star options for greatest teams and one of the best defenses. Like that Baltimore team with Dilfer and a stifling defense, or the 85 Bears - it goes down as one that will not be lumped in with all the others.
For that fact alone, even if the team does nothing else for 5+ years (doubtful though) it will still have been an amazing accomplishment beyond even the typical SB winner.
We watched one of the great teams bullrush through its schedule to dominate in a SB. And it was one of ours.
