Players v-cut their way up and down the court, with their up in front of their chest (ready to catch an imaginary pass).
Take 2-3 paces to the right and (cut) change direction and speed, then 2-3 paces to the left etc.
In addition to this, when players hear the whistle blow they must stop as quickly as possible.
A one count stop is executed. On the second blast of the whistle players can continue to v-cut their way up the court.
Triple threat position:
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.
