Players take it in turns to run from the sideline to the centre, behind the chair, where they receive the pass from the feeder.
Upon receiving the pass players must feint their way past the chair, dropping a shoulder and pretending to run one way, before pushing off from their outside foot and driving in the other direction.
Once they've got past the chair players should have a shot on goal.
Look for a clear change of pace and direction when practising the feint - even though they're only practising against a static object players should still try to make the movement as realistic as possible.
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.
