Sounds like the D we ran when Fisher first got here. The year we opened against DET and barely lost. I believe we had 52 sacks that year.
The sack totals are such an over rated stat.
Teams specifically game planned against this pass rush by getting ball out in a lot of 3 step drops and quick throws. The best way to combat it by tackling. And that was the single biggest area of improvement over the second half of the season for this defense.
As for the simplification, I agree with many here. Its more about eliminating things they know they didn't do well. And building off the things the did.
The install can be overwhelming. I have always believed in ramping things up during the season. Throw more at them as the season progresses and save some stuff that you don't show early on.
