You have a great site and it has truly blessed me on the court.
Good coaches know that developing good shooting habits takes time.
They are patient with their players and always demand players practice proper shooting mechanics. With a defensive player in place to force the shooter to rush the shot, the player takes their shots. The coach looks for the player to maintain their regular tempo, to not rush the shot. I am a brand new coach and know virtually nothing about the game except what I learned over thirty years ago in elementary school. I am in a panic.
