Seven players with two balls. One player is based at the circle of the free throw line (Player 2). Player 1 passes to player 2, player 1 who makes a cut and goes for a hand off pass. Player 1 passes to player 3 and goes to replace player 3. The same happens on the other side of the court using players 4, 2 and 5.
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.
