Lazor has been bashed plenty for a number of things, including failure to run the ball enough, poor situational play-calling on 3rd downs and in the red zone, and for stuff like too many wide receiver screens that don't work.
You're just not a credible poster. You close your eyes to things you don't want to read as you sit here making excuse after excuse for a defense that simply sucked in the back half of the season. You find one magic bullet stat that you are clinging to like a life raft, nevermind that we scored more points than 4 playoff teams and were ranked 11th in points per drive.
The only two teams that scored more points per drive than Miami that failed to make the playoff were the Saints and Falcons, both of which have truly awful defenses. This is despite the fact that our offense had one of the toughest slates of defenses to go up against of any team in the league this year.
DVOA rank: Offense 7th, Defense 17th, Special Teams 32nd
SRS rank: Offense: 8th (2.9), Defense: 18th (-0.4)
But oh, that's right. Our offensive efficiency relative to the league average and strength of schedule is somehow because of our GREAT defense. I forgot.
