2-3 Top

Purpose

2-3 Top is a defensive shell drill for teaching how the top of a 2-3 zone handles a ball at the top/right slot, a high-post flash, and the first pass down to the right wing or corner.

Use this when your zone is giving up clean catches at the nail, when both top defenders are chasing the ball, or when the bottom-line defender is late closing out to the wing. The goal is to keep the ball contained at the top, bump the high-post flash with the correct top defender, and transfer the ball to the right-side low defender without opening the middle.

This is a good next step after teaching 2-3 Base Rotations, and it connects directly into 2-3 Wing once the ball is passed down the sideline.

Setup

The defense is in a 2-3 zone.

1 is the Point Guard and starts as the lower/right top defender, closest to the ball.

2 is the Shooting Guard and starts as the higher top defender, responsible for protecting the high-post area when the offense flashes a player to the nail.

3 is the Small Forward and starts as the right-side low defender. 3 must be ready to close out to the lower right wing or corner when the ball is passed down.

4 is the Power Forward and starts as the left-side low defender, staying attached to the opposite-side wing and lane area.

5 is the Center and starts in the middle of the zone, protecting the paint and rim.

Offensively, 1 has the ball at the right slot/top area. 2 is spaced on the lower right wing or corner. 3 is high on the opposite side. 4 is on the left wing area. 5 begins low and flashes up toward the high post.

Execution

1. The ball starts with offensive 1 at the right slot/top area. Defensive 1 closes to the ball with an angled stance, taking away a direct drive into the middle.

2. Defensive 2 stays connected to the top line but shades toward the high-post area. 2 cannot stand flat beside 1. The job is to protect the nail and be ready for the high-post flash.

3. Offensive 5 flashes from the low interior area to the high post. Defensive 2 bumps that flash and takes away the easy catch at the nail. Defensive 5 stays in the paint instead of chasing the flash out of the lane.

4. When the ball is passed from offensive 1 down to offensive 2 on the right wing or corner, defensive 1 sinks with the pass for a temporary bump. This prevents an immediate inside pass while the bottom-line defender rotates out.

5. Defensive 3 closes out from the right side of the bottom line to guard the ball. The closeout should be under control: stop the catch-and-shoot first, then contain the baseline without giving up a middle drive.

6. Once 3 has taken the ball, defensive 1 recovers back toward the top-line gap. Defensive 2 stays aware of the high post, 5 stays central in the paint, and 4 remains home on the opposite side.

7. If the ball is returned to the top, the two top defenders reset. 1 takes the ball, 2 protects the high-post flash, and the bottom three defenders reform the back line.

Reads

The first read is the ball at the top. Defensive 1 is the on-ball defender. Defensive 2 should not also chase the ball. If both top defenders step to the ball, the high post is open.

The second read is the high-post flash. Defensive 2 must meet the flash early, preferably before the offensive 5 can turn and face. The goal is not to gamble for a steal. The goal is to make the high-post catch difficult and keep the ball out of the middle.

The third read is the pass down to the right wing or corner. Defensive 3 closes out on the pass, not before it. If 3 leaves early, the back line stretches and the paint becomes vulnerable. If 3 leaves late, the offense gets a rhythm shot or an easy wing entry.

The fourth read is defensive 1’s recovery. 1 bumps down only long enough to protect the pass window. Once 3 has the ball covered, 1 must recover to the top so the zone is not left with only one top defender.

Teaching Points

Coach the top two defenders as a pair. The rule is simple: 1 has the ball, 2 has the high post. They should move together but cover different threats.

Defensive 2 should arrive on the high-post flash with a hand in the passing lane and the body between the ball and the cutter. Do not let 2 drift behind the flash. A late bump is not a bump; it is a recovery.

Defensive 5 must resist the urge to step out too early. The Center protects the rim and the middle of the lane. If 5 chases the high post while 2 is already there, the defense gives up the low block and offensive rebounding position.

Defensive 3’s closeout should be inside-out. 3 should close with short steps, high hands, and enough balance to stop the baseline drive. Flying past the ball turns a correct rotation into an immediate breakdown.

Defensive 1 must communicate while bumping down. Use a clear call such as “wing” or “bump” so 3 knows to close out and 2 knows not to abandon the high post.

Keep 4 disciplined on the weak side. 4 should not drift toward the ball unless the drill expands into a full skip-pass rotation. In this segment, 4’s job is to keep the opposite side covered and protect the back line.

Common Mistakes

The most common mistake is both top defenders chasing the ball at the top. This leaves the high post open. Correct it by assigning the responsibilities clearly: 1 pressures the ball, 2 protects the nail.

Another mistake is defensive 2 bumping the high-post flash too late. If 2 waits until the offensive 5 is already at the nail, the offense can catch, turn, and pass before the zone is organized. Teach 2 to move as the cutter moves, not after the catch.

Defensive 3 may also close out late to the wing or corner. When that happens, the offense gets a clean shot or a direct drive. The correction is to make 3 move on the pass while 1 gives a short temporary bump.

Defensive 1 sometimes stays too low after the wing pass. This opens the top for a return pass. Once 3 has taken the ball, 1 must recover back to the top-line gap.

Defensive 5 may step up to guard the high post even though 2 is already there. That creates an open rim area. Keep 5 central unless the high-post catch is made and the ball is turned aggressively toward the lane.

Variations and Counters

Run the same rotation on the left side. Mirror the responsibilities so the opposite top defender takes the ball, the other top defender protects the high post, and the opposite low defender closes out to the wing or corner.

Add a live return pass from the wing back to the top. This forces 1 and 2 to reset their top-line spacing instead of relaxing after the first closeout.

Vary the timing of the high-post flash. Send 5 early, on the catch, or just before the wing pass. Defensive 2 should learn to protect the flash without losing awareness of the ball.

After the wing closeout is clean, continue into 2-3 Wing so players learn how the top rotation connects to the next part of the zone.

FAQ

Who guards the ball at the top?

Defensive 1 guards the ball. Defensive 2 protects the high post and should not duplicate 1’s job.

Should the Center step up to the high post?

Not on the initial flash. Defensive 5 stays in the middle while defensive 2 bumps the high post. 5 should protect the rim and paint first.

When does the low defender close out?

Defensive 3 closes out when the ball is passed down to the right wing or corner. 3 should not leave early, but must move immediately on the pass.

Is this a trap?

No. This is a base 2-3 zone rotation. The defense is containing the top, bumping the high post, and transferring the ball to the wing defender without overcommitting.
