Set up the same as the original lay up drill. Players in the right line pass to a player in the left line, they then receive the ball back to make a lay up. The left lane gets the lay up and passes to next player without ball in the right lane and joins the back of the right lane. The shooter leaves their shot and joins the back of the left lane. This can be done on the left of right hand sides
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.
