From the block do a spin back, drop step to the power box, lift fake from the chin position, jump step to a hook.
Concentrate on not bringing the ball down below the shoulders.
When shooting learn to keep the ball up from the chin position. If you move that ball even a centimeter away from that body the defender will be able to knock it away.
Do twenty each side of the double drop step.
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.
