This is an absolute treasure! I salivate over this.
Even though the plays are different, the philosophy is the same. I have been reading through the first one and I am already picking up a lot.
I did not know that only secondary blitzes on seven man protection triggers sight adjust. I will be looking out for that- I bet they still do that.
6 man protection = quick throw mentality. Let's see if that is still there.
There is a lot of handwritten notes on the pass/run protection schemes which leads me to think that this particular playbook came from an OL, probably on the right side. I would go as far as to say it came from a backup OL, right side.
I am only halfway through on the first PDF and there is so much detail to absorb.
