Defending 4 on 4 shell

| 1 Initially have stationary attackers, no skip passes, and attackers hold the ball for 1 or 2 seconds before passing. As attackers pass around the perimeter, defenders jump with the ball into proper on-ball and off-ball positions (be there on the catch), use a quick crossover step then sprint to your spot. One pass from the ball, deny or gap (see Defence - Basic halfcourt man defences for these and other options).
Progressions
- skip pass - pass and basket cut (Wootten Fogler, Memphis) - dribble penetration (Wootten horseshoe, Pitt 4 on 4 penetration, Forcing left, Memphis) - ballscreens (4 on 4 ballscreens) - off-ball screens (Tar Heels, Pangos beat the screen) - contest passes (Tar Heels) - post defence (Florida, Green) - 5 on 5 - go live after X passes, on "go", or after specified offensive action.
Option - on coach's signal, defenders rotate one position. |

| 2 An unbalanced shell drill can be used to work on defending forwards or guards. The attackers without defenders cannot shoot (option - or dribble).
Examples (Coach K)
- 5 on 2 with defenders only on the posts (shown) - 5 on 3 with defenders only on the perimeter players - 5 on 4, coach determines which player does not have a defender - 5 on 5 but only one or some attackers can score, defenders do not know who they are.
2007 Tasman Coaches Clinic - add a 5th attacker, unguarded, who dribbles at gaps to force rotations and help. Build to 4 on 4 live, 3-dribble maximum.
Tom Izzo - play 4 on 3 and 5 on 4, a weakside defender has two attackers. Tony Barone - play 4 on 4, 5 on 4 (attacker at the high post), and 6 on 4 (attackers in the corners), see Scrimmage - Spurs 4 on 4 on 4. |
