Quarterbacks and QB coaches…Be extremely cautious about “copying” a throwing motion…Every human body is designed uniquely different… the motion needs to be as quick and compact as possible that allows the maximum velocity…To get to that each body has to adjust, especially when u are still growing… A great coach will begin with his basic philosophy but will adjust to each individual structure…Philip Rivers is different than Lamar Jackson…And Peyton Manning is different than Caleb Williams…Do what works and adjust in the offseason…Don’t “coach or adjust” a motion during the season or a game. It’s an off season project
