I found this video on YouTube and he really does a great job of illustrating how the Bills defense is played and how insanely well coached the unit is. This is just a breakdown of week 1 against the rams, but really shows how disciplined and fundamentally sound the defense it. It also helped me to gain more appreciation for how well coached this team is. The defensive calls were perfect, countering everything the Rams wanted to do and really showed they were one step ahead of them at every turn. We saw this against the Titans too.
I also gained a lot of respect for Tremaine Edmunds from watching this video. He is asked to do a lot and is very effective in coverage. He had a good game week 2 as well, with a sack, 2 tackles for loss, a QB hit, and a deflected pass that was intercepted by Poyer.
