Practice doing virtual variations of different moves, for example do a spin back at the top of the three point line in a guard position, forward pivot to a triple thread, head and shoulder fake to the middle, dibble drive to the baseline, do a spin fake and drive on the baseline to shoot a reverse layup.
You will need to simulate different type game situations.
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.
