Derek Carr - Why People Dislike Him (IMO)

The game evolves. There are wrinkles. Verbiage is different, Architecture of an Offense is different. Every team has a wrinkle of West Coast. San Francisco runs some power T concepts. Every team runs RB power. Every team runs mesh concepts, and 4 verts. If you have a QB that can diagnose a Defense. Has the sense to audible into a play. That is not a system QB. His system did not teach him to diagnose cover 1 from a safety blitz from the A Gap. Put a man in motion to recover zone from man. In a 3 rd and short. Then audible to a run play to get the first down. His system will teach him progressions.Verbiage. Very rarely are teams going into a 3-5 step drop on timing. This happens sometimes. This is not the 80’s. There are plays design. The slant is one. Football I.Q. Is amazing. Playing QB is like hitting a baseball. Trust your read, analyze. You are only going to have 3 to 4 seconds to get the ball out. What is the situation. Know where to go with the Ball. If you hold the ball a half a second too long. You better scramble. You are already too late. A system doesn’t make a QB. If it did. The Browns would just run the same Offense Texas A & M did with Johnny football regardless of the Defense, and talent.
Timing has always been an element of what we implemented into our system and you would be surprised on some of the offenses that still rely heavily on timing. But that's another discussion that talks about actual QB skill vs reliance on skill players that meant for another day . Diagnosing a defense comes from film study and knowing how to manipulate this comes from understand the playbook. But it seems like a lot of people are mistaking what I'm saying. I'm not saying that the system teaches someone how to play QB nor saying that the system replaces football IQ but I'm saying that the greatest QBs in the league have the vast experience in a single system as a common denominator.

Also, your point about Manziel slightly misses the mark because he just did what he wanted to in college and it just worked but I remember Merrill Hodges said that it was nothing on film that would make him take him as an NFL QB..lol. And if you pay attention to the QB position now, most are pulling elements from college into the league to help the QB. This is part of the development that Tom Brady was talking about.

Nope, with field vision, QB's either have it or they don't.....experience is important in other aspects for sure but very few guys have a sense of where players are "going to be"......Captain measurable type QB's like Herbert and Josh Allen could play 10-12 more years and still won't have it.....
Manning had elite field vision, but he also turned he ball over at a much higher rate than most in the league for a good bit of time.
