Football Outsiders is good for stats like this.

I posted several last week. Through 3 weeks Miami averaged 0.6 more plays allowed per drive than the average which had them ranked 27th and 1 more defensive drive per game. In short, Miami was playing 13.2 more defensive snaps per game than the average team. They also ranked 25th in time allowed per drive at 3:01. The we're 31st in 3 and outs percentage.

That was offset by a better than average punt percentage and red zone scoring percentage. In short, they're playing a bend but don't break style which is keeping them alive.

Offense needs to do its part however because Miami's defense is being asked to shoulder too much of the load.

 

it's a lose-lose situation.

 

Bend, but don't break only works if your offense can outscore the other team.

 

yes and like most years the defense will break at the end of the year.
