Player on the baseline is a cutter and player on the top is a passer.
The cutter runs towards the key until one foot is inside the key then they change direction and move towards the ball. When they are free they must signal for the ball with their outside hand.
Once they receive the ball they can then square up towards the basket and go for a shot or drive for a lay up.
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.
