One of the main tenets at Football Outsiders states that offense is more consistent than defense. This is true between seasons, but it's also true during a season. So the best way for an NFL team to be taken seriously as a Super Bowl contender is to get off to a strong start on offense. That team is likely going to be winning games all year.
So after six weeks, we want to take a look at the best offenses in the NFL. Where are they strongest and weakest, and what has changed since last year? Offenses are ranked using our DVOA (defense-adjusted value over average) ratings, which score every single play's success based on down and distance then compares it to a baseline, adjusted for situation and opponent.
