Footwork is always important in executing a correct lay up shot.
Shooting from the right side, the player should lead off their left foot and reach up to the basket extending right arm up towards basket at the same time as keeping the right knee bent to aid lift.
Aim to place the ball on the backboard so that it rebounds back into the basket.
Rebounding is the least glamorous thing in basketball and one of the most decisive. It is also almost entirely a habit, which means it is entirely coachable.
Good spacing is only the start. The best modern offences teach players to attack the defence's rotations and play in a permanent 4-on-3 - here is how to coach that read.
The ball screen produces almost half of all professional offensive possessions, yet most teams still teach it as a memorised play. The modern approach trains the read - giving players a framework to decide based on what the defence does, not what the coach called.
