How did guys like Larry Bird ever shoot the ball so well before analytics software? LOL!
There is such a thing as over-thinking the problem.
Give me an old school coach who can help a kid with his physical mechanics...getting feet and hips set/square to the basket, good lift and straight back, bent elbow and a snap follow through...along with helping him get to a good place mentally with his shot. When mechanics are good and you have the proper mental focus, it then comes down to repetition and muscle memory.
Shooting the ball should be second nature, not a "event".
