You give little thought to the actual shot when working on technique. Conversely or inversely or reciprocally, thinking about technique when in the motion of shooting can only psyche you out. These two things should be practiced, and even more importantly, thought about separately. If you are a good shooter in practice, then you should be a good game shooter. Shooting rested, under little psychological pressure or physical defensive pressure in practice is not the same as shooting under more adverse game situations.
Good shooters are good game shooters.
You need talent to shoot well. Only naturally talented players can shoot well and learn tricky moves. Anybody can be a good shooter or dribbler, passer, etc. Great shooters are great players. Note that many Hall of Famers are not great shooters, so you can be a great player without being a great shooter.
