2. Points per game. Ultimately, this is the only stat that matters. The Dolphins' offense has gone from 19.4 points a game (27th in league) last year to 22.6 this year (17th). Let's not go crazy with this improvement as they scored 24.3 points in 2014. But couple what the offense is doing with what the defense is doing to understand this year's turnaround. Last year, the defense gave up 24.3 points a game (19th). This year, it averages 21.8 points (16th). So the offense is scoring 3.2 points more a game and the defense is giving up 2.5 less a game. Together, they explain why they're 7-4 right now.
