Player 1 passes to player 3 who then passes to player 2. Once player 3 has passed the ball he then runs to player 1 and shouts "Go", player 1 then goes to where player 3 was. Player 2 then passes to player 1 and they then pass to player 4.
Player 1 then runs to player 2 and exchanges positions.
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.
