Player 1 passes to player 2 (can be the coach) before making a run and then cutting to the next cone to receive the pass.
Player 1 then dribbles to the next cone before having a shot.
Drill should be continuous. After the shot players collect their ball and dribble up the court to join the back of the line.
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.
