Instructions

  1. The offensive player walks or dribbles slowly within a small area while the defender stays an arm's length away at all times.
  2. The defender keeps hands up and active but is not allowed to reach in and try to steal the ball.
  3. Switch roles after 30-45 seconds.
  4. Progress to the offensive player moving a bit faster once the spacing habit is solid.
Coaching Points
  • An arm's length away is close enough to contest but far enough to react.
  • Active hands, not grabby hands - the goal is discouraging a pass or shot, not fouling.
  • Stay on the balls of the feet, ready to move in any direction.

Variation

Add a second defender for a very basic 2-on-1 shell look.
