At least that is an actual discussion of technique, so we're moving in the right direction. He still has a ways to go to demonstrate that Ryan made that mistake because he was coached to do it. Couldn't have had just made a mistake? To really prove that you'd either need to see every single non-FA corner making that mistake regularly or you'd need to demonstrate that guys like Dennard and Ryan weren't making those mistakes in their rookie/college years but do now.
Still a long way to go, but it's more convincing that just saying, "they're not as good so the coaching must suck!"
You'd also have to have coached defensive backs and realize that some have much more native athletic ability than others. I appreciate that he watches film, just like some posters here, who also have the advantage of having coached or played more than one year of high school football.
I just think it's really presumptuous of him to criticize the coaching staff because some other writer showed him how to watch film, so now he is the expert on coaching cornerback technique. I guess you'd call that jumping the shark.
But, most of all, the entire story of our team is now a coaching staff that fails to teach cornerback technique, based on one game where, arguably, the best QB in football worked all week at, and executed, a game plan based on attacking with anyone except his top two receivers. Given we allocated out top 2 CBs and safety help elsewhere, this plan, executed well, had a good chance against any team, including one with great QB depth.
The Patriots did not adjust. Next week, when a backup CB plays well, the story will be how we have invincible CB depth all the way to the inactive Butler or Dennard. Each story will be a BS over reaction to the previous game and the fans will eat up the writer's "expert" analysis.
