Overall the front 7 looked way more fundamentally sound than it did under Quinn, that could be due to Zimmer's focus on stopping the run, not wholly relying on 295 lb. DT's, or just the fact that we've actually invested in LB's, but it was apparent.
The one play that really drove this home for me was 3rd and 4 around midfield in the 3rd when we were up 27-10. How often over the last few years have we complained about being in 2nd and 7 or 3rd and 5, normally passing downs, and offenses would run a simple draw and pop it for 5-7 because our pass rush was recklessly flying upfield?
That 3rd and 4 was the exact same situation where we'd have given up a soft 5 under Quinn, but yesterday it went for a loss of 2, put them in 4th and 6 and led to a stop.
The pass rush didn't look quite as dynamic as it did under Quinn but I think the floor for the defense is much higher. There will surely be a few tough games and growing pains but I think Zimmer's defense is just structurally better than Quinn's and I'm glad to see the players taking to it.
