This drill informs players what to do when they have passed the ball. After a player has passed the ball they must cut and weeve. In doing so it gets players into space. After a player has passed and cut through the opposition another player on the offensive team must replace. Again this creates space between the attacker and the defender.
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.
