Three players (1 defender and 2 attackers). Player 1 runs towards the defender before making an S-Cut and receiving the ball from Player 3. Player 1 then turns and shoots before colecting the rebound and throwing it to player 5.
Player 3 then goes into be the defender, with players 4 and five as the attackers.
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.
