Derek Carr - Why People Dislike Him (IMO)

Yet, you named 3 QBs that has only played in 1 system their entire career, 1 who excelled in his 2nd system that was built just for him, and 1 who was in the same system for 20 years, tried something new, and went back to what he knew before the season ended.

You telling me Mahomes can play in an offense where he has to take 5 or 7 step drops from under center while reading the entire field and throwing a pass on schedule? Probably not because that is not a part of his skill set and never was. And becausewe are in a time where skill players matter more than "QB skill," he probably never will. If he ever goes to another team, they will not be putting that in the playbook. Honestly, if he goes to a different team, if will be bringing what he did in Kansas City with him, because that is what they all do..lol. We are arguing about if they will succeed in another system when they themselves (outside of Brady for less than a season) never tested the waters.
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.
