I have posted this guy's work several times. Twice a poster, the same guy, made a remark the Scout has wrong about his assessments. Not certain I agree with that comment. But like so much of what is posted here, opinions are painted as facts, and seldom have any explanation as to why the critic thinks the Scout was incorrect.
My contention, and this is opinion, the passing game needs to be practiced daily for the components to accomplish their goal. Rusty has a connotation this is the passer out of sync.
I go back to Quincy Carter and his epic failure in the Cardinal game that got him benched and in a clear cut screaming match with Jerry on the sidelines.
Read/react is an aspect of the passing game. I am not clever enough to know when that is taking place or not. But for this to work, both the quarterback and receiver must see the defense the same and conclude equally where the route is to be run.
To me that comes down to practice. Six weeks off, with little to no pre-season in-game conditions, MIGHT throw off the QB. But then there are so many variables, and I am not an expert I could be way off on this.
