Box and 1 - Shell Drill

In this drill, we are removing the chaser and focusing on the box zone principals.


Teaching Point:

Imagine the box is connected by rubber bands. When I point to the wing, the entire box shifts that direction while maintaining its shape. Top defenders adjust their depth, bottom defenders pinch or widen - but they move together.


Common Mistakes to Watch:


  • Box getting too wide or narrow
  • Defenders moving individually instead of as unit
  • Weak side defenders not shifting far enough
Phase 1: Static Rotations (3 minutes)

Set up 4 defensive players in box formation (two high, two low). Coach stands at top of key with one basketball.


  • Coach points to different perimeter spots (wing, corner, opposite wing)
  • As coach points, entire box must shift as a unit to match ball position
  • No passing yet - just teaching box movement and spacing


Teaching Point:


I'll typically start by pointing slowly to each spot, then gradually increase the pace as players grasp the concept of moving together.

Phase 2: Pass Recognition (5 minutes)

Add 4 offensive players around perimeter.


  • Offense passes ball around perimeter only
  • No dribbling, cutting, or screening
  • Defense rotates with each pass
  • Must call out "Ball!" or “Help!”


Teaching Point:


Start slow and then build up from there. Keep the passing from one spot to the next to start, and then increase the speed and add skip passes once they understand the movements and spacing.


Common Correction:


If you see your box players getting too spread out, stop the drill and have them all take one step closer to each other. Tight spacing is crucial - I'd rather have them too close than too far apart.

Phase 3: Live Movement (7 minutes)

Offense can now cut and screen.


  • Defense must communicate every cutter
  • Add scoring element: 
  • Defense gets point for deflection/stop
  • Offense gets point for paint touch
  • First team to 5 points wins (loser has a consequence)


Teaching Point:


When the offense scores, have them explain where the breakdown occurred. This helps players understand their responsibilities and builds defensive IQ.


Often they'll identify the mistake before I need to point it out.
