If hes not takin in-game shot how do you suppose hes going to improve?
Practice, experience, and film.
By your logic, how can players make the big leap in production during the offseason between their freshman and sophmore years when they arent taking in game shots?
Practice, experience, and film.
Practice to work that hitch he so clearly has out of his motion.
Experience to understand when to shoot and when not to shoot.
Film to help highlight when to shoot and when not to shoot.
Kegler can absolutely improve. If he eliminated half of the bad shots, meaning he flat out didnt shoot some of the terrible decision shots, he would improve and make the team better. Perhaps instead of an illadvised shot and defensive rebound(essentially a turnover), he drives into the paint and is fouled for freethrows. Or perhaps he drives and collapses the defense so a kickout to someone open on the perimeter allows for a higher % shot.
Improvement thru reduction.
While I have maintained that there is no stat for bad shots and ALL shots are used to determine if someone is a good shooter or not, I do recognize that if someone were to reduce the bad shots, they effectively become a better shooter. He needs to do that and the sooner the better. Film will help show the differences.
Kegler doesnt need to have the greenlight to shoot from anywhere to improve(another way of interpreting what you seem to suggest). Thats a crazy way to coach.
