This video really pointed out a lot of what I had been seeing in our defense that I personally couldn't describe as intelligently as he did, so thanks for posting this.
Some important points I think he made that apply to our situation:
First, this scheme, as mentioned, was designed to attack a specific type of NFL offense. It's designed for Kyler Murrays and Russell Wilsons. (Originally it was aimed at Mahomes, but Mahomes has proven that he's far better at adapting his game than those two guys). Yet, our major downturn defensively in this season is when we took a hard turn back to these concepts against Tom Brady. You couldn't ask for a more ridiculous opponent to try and run this scheme against. That is a major knock on our coaching staff.
Second, I think one thing he points out is that this scheme requires some ridiculous talent at basically every single position on the defensive side of the ball. Your DL needs to be adept at two-gap tech, your LBs need to be great at reading and reacting to your DL AND need to be great at shedding blocks, and your secondary needs to be almost automatic in switching assignments and handing off. Here is a problem for us: Our front 7 has been built around Pete's much simpler one-gap tech pretty much forever. Barton, in particular, is not great at reacting or shedding heads up blocks (though I think he is underrated in other aspects of his game). And while this system really plays to the strengths of an elite talent at safety like Jamal Adams, he is... not here.
Third, as mentioned, this scheme is terrible against the run, and I was not aware how prevalent this problem seems to be across pretty much every team that's heavily reliant on this system. He specifically points out that teams running this scheme look almost uniformly soft, which has been an oft lamented critique of our defense on this board.
Finally, he points out that the stubbornness of the teams running this scheme in thinking that this is a miracle defense that can be run regardless of who your team is facing. In fact, it appears moreso that this needs to be run much more as a situational scheme and is a poor base defense. The Seahawks took a noticeable turn away from this scheme in the first half of the year and the results were impressive. For some reason, we took a hard turn BACK to these techniques (as I mentioned, against pretty much the worst possible opponent to do it against) and seem to be stubbornly trying to force a round peg into a square hole.
Some of this I understand: This is a COMPLICATED defense that requires teams to get a lot of reps and familiarity with each other running it. There is a problem though: We arguably barely had the talent for this scheme when we had our very expensive Safety healthy and on the field. We definitely do not have it right now.
And more importantly, the question for me is: Is the juice worth the squeeze? Losing winnable games now to try and build familiarity with this system for the future? After watching this video, I feel even more confident that the answer to this is NO. It's not.
