You need to cut your "efficiency" crap. This is not the "#2 most efficient D" under any circumstances. They give up the 2nd most yards and 14th(?) most points. The only thing we've done a great job at is creating turnovers, that is NOT something you can bank on every game.
What evidence do you have of our "#2 defense" slowing down the average offense?
We gave up 488 yards and 24 points to Miami's below average offense.
We gave up 448 yards and 34 points to Buffalo's pretty average offense.
We gave up 504 yards and 19 points to Oakland's average-below average offense.
We gave up 427 yards and 25 points to Pittsburgh's below average offense.
We gave up 463 yards and 27 points to Washington's below average offense.
We gave up 437 yards and 24 points to Indianapolis' below average offense.
We gave up 393 yards and 23 points to Denver's "#27 offense".
We gave up 374 yards and 24 points to Miami's below average offense.
We gave up 402 yards and 21 points to Buffalo's pretty average offense.
What about these makes your think we have the "#2 defense"? Your defensive efficiency crap is garbage. The only reason we won these games is because our offense caught fire at one point or another and scored 30+ points in 12 of our 16 games.
Very few teams not sporting our offense would be able to win those games.
Yes, our defense made some stops and forced turnovers, but they still are nothing close to the #2 defense. They are what they are, the 14th best in points allowed, paired with the #3 scoring offense.
Edit: And I don't even hate our D, but they are what they are, and that is not #2. They keep too many opponents alive in games that shouldn't be, but they do make some clutch plays.
