1. Line your players up at the free throw line in single file. Give the first two players in the line a basketball.
2. On your whistle, the first player in line will shoot a free throw. If they make it, they will retrieve the ball and pass it to the next person in line without a basketball. If they miss, they must retrieve the ball and make a lay-up or standing shot.
3. The next player in line is allowed to shoot a free throw as soon as the previous player’s ball hits the rim or goes through the net. If the previous player misses, the next player is attempting to make a free throw (or rebound shot) before that player makes their rebound shot.
4. If the second player makes their shot before rebound shot is made the previous player has to sit out for the rest of the drill.
5. This process continues until only one player remains.
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.
