I enjoyed your write up and felt you covered all of the key points to our season very well.
Maybe it's just me, but it seems there are plenty out there who are very frustrated with what we have seen out of this defense. And for me, it all goes back to the 13 seconds and the fact that the Bills org seemed to dodge the whole accountability question.
We continued to see very similar "soft" schemes this past year and plenty of instances in the Bengals game. When you look at the 4 teams that played this past weekend, I would argue they all looked and played much more aggressively on defense than what we saw from the Bills at the end of the season, and all use the blitz very effectively. I would argue that we have the personnel but we're not putting them in positions to be as successful as they could be and that goes for the offensive side of the ball with players like Hines and Shakir, and not being able to effectively run screens.
The Damar Hamlin injury had to be a distraction for the Bills and probably did take some of the energy out of the locker room. But I also don't put a lot of stock in what Saffold says because he hasn't shown much energy the entire season.
