Box-and-One Defense Drill

A junk defense that assigns one defender to shadow the opponent's best scorer man-to-man while the other four play a box zone — a situational tool worth having ready for a dangerous opponent.

This junk defense just needs a ball and five defenders, but a basic coaching-aid kit keeps the rest of practice moving.

Setup

  • Four defenders set up in a box zone shape around the key; one defender is assigned to shadow the designated scorer everywhere they go.
  • Offense sets up in a normal half-court alignment with their best scorer at any spot.

Instructions

  1. The chaser defender denies the ball to their assigned player everywhere on the floor, including off-ball screens.
  2. The box-four hold their zone shape, sliding to cover gaps as the ball moves.
  3. If the designated scorer gets the ball anyway, the nearest box defender helps immediately.
  4. Play out full possessions and rotate offensive personnel to test the coverage against different looks.
Coaching Points
  • The chaser must fight through screens rather than switching — losing the assignment defeats the entire defense.
  • The box four need constant communication since their shape has to adjust to where the chaser and ball end up.
  • This defense is vulnerable to strong ball movement away from the star player — rep that scenario specifically.
  • Use this as a situational tool, not a base defense — practice entering and exiting it smoothly.

Variation

Have the offense specifically design plays to free their star player to stress-test the chaser, or switch which defender plays the chaser role to build depth.
