This drill requires 3 players around the basket with one feeder/coach.
The ball is thrown up at the basket, the players will battle for the rebound.
The player who gets the rebound gets to leave the drill and joins the back of the line and a new player will come in.
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.
