ESPN Insider, with the help of Football Outsiders DVOA advanced metrics system, has decided to rank the best offense, defense, special teams, and overall teams in the last thirty years every day this week. They ranked the best thirty defenses over the last three decades a few days ago, and six Baltimore Ravens defenses were among them. Which is a clear testament to what the team has accomplished in its 21-year history on that side of the ball.
On Thursday, it was time for the people at Football Outsiders to list the best teams over the last thirty years according to their DVOA system.
