First stage in dribbling ball between the legs. Start with feet shoulder width apart, bouncing the ball outside the right foot. Lead forwards with left foot. As the foot plants and the weight transfers forwards, bounce the ball under the leg and collect it with the left hand.
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.
