How it works
- 1
Set the box
Your best passer (usually 3) takes the ball out. 5 and 4 occupy the blocks, 1 and 2 the elbows, all facing the inbounder. Everyone holds until 3 slaps the ball — the universal trigger.
- 2
Option 1 — Screen the screener
On the slap, 2 drops from the ball-side elbow and cross-screens for 5, who cuts low across the lane to the ball-side block for the layup pass. A beat later, 4 down-screens for 2, who pops to the top of the key. First look rim, second look the pop-out jumper.
- 3
Option 2 — Shooter special
Same start, but 1 and 4 set a weak-side stagger for 2, who curls off both screens to the corner for a catch-and-shoot three. 5 flashes ball-side as the decoy that pins the help low.
- 4
Safety and re-entry
If both options are denied at the five-second count, 1 sprints to the ball-side wing as the safety. 3 hits 1, steps inbounds to the weak-side corner, and the team flows into half-court offense — never burn a timeout to rescue a denied BLOB.
- 5
Vs zone defense
Against a 2-3 zone, keep the box but overload: 5 screens the back line's middle defender while 2 slides to the short corner. 3 reads high-low — the short-corner catch forces the back line to commit, opening 5 sealing inside.
Coaching points
The inbounder is your play-caller: choose a calm passer who can fake high and pass low off the same look.
Cutters leave on the slap, not before — early movement lets defenders slide through the lane untouched.
Screeners hold their block until contact; the screen-the-screener sequence dies when the first screener drifts early to chase his own shot.
Teach the lob-height pass over the top when the defense fronts the block cut — it should drop in the four-foot window between rim and helper.
Variations
Box flat counter
Start in the box, then drop all four players to a flat line along the baseline before the slap. The late shape change scrambles pre-switched assignments and opens the elbow for a back screen lob.
Same set, three calls
Number the options — 'Box 1', 'Box 2', 'Box 3' — and run all three from an identical start; scouting becomes useless when every call opens the same way.
Build it in Coach Board
Draw the box once in Coach Board, then duplicate the board for each numbered call and animate them separately — cross screen first, down screen a beat later. Slow the playback to half speed so players see why the second screen gets open, then share the set as a link before game day.
