Players work in groups of 3, with one ball per group.
The ball starts on the side with two players. The first player in the line passes to the opposite side and then follows their own pass. The receiving player catches the ball and then also passes and follows their own pass.
Drill continues. Players must move laterally from one end of the court to the other while performing this skill.
Look for good movement, as players use side-steps to progress from one end of the court to the other.
Also ensure your players step into the pass (for extra power and accuracy) and that they use a quick burst of acceleration to sprint to the back of the opposite line after passing.
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.
