Teams beat it the same way at every level: put players in seams the zone can't assign, move the ball faster than five defenders can shift, and make somebody guard two attackers at once. The framework overlays a 1-3-1 on the 2-3: a point guard splitting the top guards, wings at free-throw line extended, a flash player at the high post, and a baseline runner between short corners. Every principle — gap attacks, skip passes, screening the back line — flows from those spots. ## Objective Generate layups and open catch-and-shoot looks against a 2-3 zone by occupying the high post and short corner, shifting the zone with reversals, and punishing slow rotations. ## Setup - **Area:** Half court - **Players:** 5v5 (walk through 5v0 first, then guided 5v5 against a set 2-3) - **Equipment:** 1 ball - **Duration:** 15–20 minutes per install block - **Level:** intermediate (U13+) ## How it works 1. **Overlay the 1-3-1** — 1 splits the two top defenders, 2 and 3 hold the wings at free-throw line extended, 4 flashes to the high post, and 5 slides short corner to short corner along the baseline behind the back line. Every player now sits in a seam between two defenders. 2. **Shift the zone with reversals** — Swing point-to-wing-to-point-to-opposite-wing, no dribbles, nothing held longer than two seconds. After two fast reversals the bottom defenders arrive a step late — that step is the short-corner and high-post window. 3. **Play through the high post** — Whenever the middle opens, hit 4 flashing to the free-throw line. He pivots to face the rim: first look is the high-low to 5 sealing the middle defender, second is either corner shooter as the back line pinches in. 4. **Attack the gaps and play inside-out** — From the wing, 2 drives the seam between the top guard and the bottom-corner defender — two dribbles, stop, and read. If the corner defender steps up, drop it short corner to 5; if the top guard chases, spray it back to 1 relocating behind the ball. 5. **Skip and screen the back line** — After an overload pulls the whole zone ball-side, throw the skip pass over the top to the weak wing. As the bottom defender sprints to close out, 5 back-screens him mid-rotation — the shooter fires or hits 5 slipping to the open block. ## Coaching points - Feed the middle every third pass or so — a 2-3 that never has to guard the high post is playing at half difficulty. - Catch on the hop with shoulders square; against a zone, the half-second saved on every catch compounds into open shots. - Drive to pass, not to finish: gap attacks make two defenders commit, and the kick is the point. - Crash the offensive glass from the corners — zones have no box-out assignments, and weak-side rebounds are the zone's structural tax. ## Variations - **Overload the ball side** — Slide 1 to the ball-side corner so four attackers fill one half: corner, wing, short corner, high post. Three defenders cannot cover four spots; the ball finds the fourth. - **Screen the top** — Have 4 step out and screen the ball-side top guard while 1 dribbles off it into the seam. The zone must trap, lift the back line, or concede the free-throw-line jumper — each answer opens a pass you can pre-teach. ## Build it in Coach Board Set up the 2-3 zone as opponent tokens in Coach Board and animate the defenders shifting on each pass, not just your own players — zone offense is about what the ball does to the defense. Loop the two-reversal sequence and pause where the back line arrives a step late — that frame teaches the timing of the short-corner pass. ## FAQ ### What is the weakest spot in a 2-3 zone? The high post at the free-throw line, followed by the short corners along the baseline. Both sit in seams between defenders, so no one in the zone is fully responsible for them. A catch at the high post lets the offense play high-low and inside-out against a collapsing back line. ### Should you dribble against a 2-3 zone? Sparingly and with purpose. Reversals by pass shift a zone far faster than any dribble, but short two-dribble gap attacks that force two defenders to commit are essential. Avoid the aimless perimeter dribble that lets the zone rest and reset. ## Related - https://coachboard.app/library/basketball/1-4-high-entries.md - https://coachboard.app/library/basketball/horns-set-plays.md - https://coachboard.app/library/basketball/press-break-vs-diamond-press.md --- Animate and share this tactic with your team: https://my.coachboard.app
