Two players (blue) with the ball start from the half way line. They're playing against Red 1 and Red 2.
After the attackers have had their shot the 2 defenders must box out and claim the rebound.
Once the drill is complete players rotate:
Attackers become the new defenders, the defending pair leave the court and swap with a new pair who are the new attackers!
Continue until every pair has had a go.
Show a target when receiving a pass.
Pushing the ball at speed up the court.
If the attack claim the rebound they should have another shot.
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.
