Players will set up as shown in the animation. With the basketball starting in the corner line.
The ball will be passed from the corner to the line at the top.
Once passed that player will run towards the free-throw line and receive the ball back.
When that pass has been made, the player from the top line will run around the cone and towards the basket where they will receive the ball for a shot.
Players will switch lines.
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.
