This is the position a player needs to have when positing up to receive the basketball.
The player needs a wide stance, knees bent and hips low.
The hand they want to receive the basketball with should be extended out away from the defender.
The other arm, should act as a barrier between the post player and defender. This bar also helps with balance and movement.
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.
