Setting Up in the Box
Start in a box formation. Put your best shooter on the weak-side low block, your best post-up threat on the weak-side elbow, and have the point guard inbound the ball.
The Back Screen
The shooter sets a simple back screen for the center, who cuts hard to the rim looking for the ball. This is a genuine first look — the point guard should hit it immediately if the defense is caught flat-footed.
The Gate Screen
The instant that back screen is set, the shooter sprints through a gate formed by the two remaining players and pops out to the wing for a catch-and-shoot. The two gate-setters have to time their arrival together — moving too early tips the defense off to what's coming.
The Cross Screen Finish
After screening, both gate-setters clear out to the top of the key, and the point guard — now empty-handed after the inbounds pass — steps in from the baseline and sets a cross screen. The center uses it to duck in and seal deep position on the ball-side low block for the easy score.
Coaching Points
The point guard should be the one to inbound the ball specifically so that the eventual help defender on the cross screen is a smaller player, not a true rim protector.
The gate-setters must arrive at the exact same moment the shooter is ready to sprint through — arriving early or late defeats the purpose of the gate.
Any pass to the shooter coming off a screen should go to his inside shoulder; a pass to the outside makes the catch-and-shoot far harder to execute.
