White Player 1 is 'On'
Blue Players 1 to 8 try to dribble their basketballs to the opposite line.
Any players that the white player touches are 'caught' and will be 'On' with white player 1.
The players that make it to the other side continue until there is one winner.
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.
