Shooting is an optimization problem. Each of us has the capability to shoot a variety of ways with some degree of success. To advocate one universal way that is the best for everyone is ridiculous. Effective shooting requires finding a balance between simple physics and anatomy - simple physics in the sense of applying appropriate force to a symmetrical sphere in order to send it into the basket. Due to anatomical differences, the best method for doing this will vary among individuals. We are all different. If I was a clone of Steve Kerr or Stephen Curry, I could imitate their shooting form with great success. However, since I am not, adjustments must be made.
