Players and cones set out as shown in animation.
The basketball will be passed from the line at the top to the player stood in the corner.
Once the player in the corner has the ball, the player in the top line will run around the cone and towards the side of the free-throw line where they will catch the ball and shoot.
The player that shoots the ball will get their own rebound and pass to the player in the corner. Who will then pass to the next player without a ball in the top line.
After the player rebounds, he becomes the next passer in the corner.
Good team defence is five players guarding the ball, not five separate one-on-ones. The shell drill is where that starts, so here is how to teach help-side positioning and rotations from the first week of the season.
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.
