All players have a ball and line up on the same cone. Players attempt a shot and if successful move to the next cone. If unsuccessful they go to the back of the line.
The drill focuses on proper shooting technique and shooting from different angles of the court.
Players should focus on proper technique which includes, arm and foot alignment, 90 degree bend in the elbow, guide hand supporting the ball and full extension of the elbow at the end of the 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.
