Players will set up as shown in the animation. With the basketball starting in the corner line.
The ball will be passed from the corner to the line at the top.
Once passed that player will run towards the free-throw line and receive the ball back.
When that pass has been made, the player from the top line will run around the cone and towards the basket where they will receive the ball for a shot.
Players will switch lines.
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.
