Each player has a basketball. At the end of each baseline put a football goal. The coach has a volleyball. Each player must hold his or her basketball with both hands (fingertips). The game starts in the central circle. The coach bounces the volleyball and players must hit the volleyball with the basketball and try to score a goal.
Rules:
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.
