12. 2013 Seahawks (won Super Bowl XLVIII)
Although just six seasons ago, it’s easy to forget just how dominant the “Legion of Boom” was that season. The Seahawks defense gave up just 172 yards passing a game in a day and age where quarterbacks are king.
With that kind of support, all Russell Wilson and the offense had to do was score every once in a while and it would be good enough to win. Yet, they exploded in the Super Bowl crushing the Broncos 43-8. They should have made it back-to-back titles the year after, but they failed to give the ball to Marshawn Lynch when it mattered most.
