A quarterback's throwing motion is a complex biomechanical process that involves multiple joints, muscles, and motor pathways. Josh Allen’s motion looks different than Brock Purdy’s whose looks different than Jalen Hurts. The takeaway from that statement is two things:
1. No one throwing motion is exactly the same, because of uncontrollable physical and environmental variables.
2. While not exactly the same, there are fundamental commonalities that all elite throwers share.
A future blog will dive into those commonalities. This blog explains the uncontrollable variables and why you should be aware of them.
You cannot control your height, arm length, leg length, hand size, foot size, ratio of torso to leg length, etc. You cannot go back in time and change your childhood which will never be exactly the same as someone else’s. You played different sports at different ages, had different quarterback coaches, and interacted in different physical environments all of which will impact how your body moves through space. What spins out from those experiences is the quarterback you are today. While you cannot change your past or your hand size, you can work to maximize the tools you have to be the best you can. Understand the core commonalities (future post to cover), work to integrate those into your motion and then embrace the uniqueness in your performance.
