defense
Two defenders farther from the basket and three nearer it combine paint protection with pressure on the ball. In Gels' version, guards normally cover wing receivers; the two outside defenders near the basket cover corner receivers.
A wing handoff between defenders, using Gels’ coverage rules with our own player numbers. X4 is the center here. This is not a corner trap.
1–5 are players on offense. X1–X5 are defenders. Each number stays with the same player in every step; it does not lock that player into a position.

1 passes to 2. X5 reaches the wing first. X2 moves across to take over.

2–3 zone: defenders away from the ball

This reference uses Gels’ selected 2-3 principles with our numbering. X4 is the center here. Trap choices are separate calls, not compulsory steps after the displayed wing exchange.
X1 and X2 start high; X3 and X5 cover the lower sides; X4 protects the middle. A lower defender can meet a quick wing catch until the high guard arrives and calls the exchange. Gels numbers the center X5; our diagram uses X4.
Source-backed summary; versions may differ.
Walk one quick reversal, then repeat with the passer holding the ball. The first defender must be able to say who replaces them before leaving. Use an observer behind the offense to check whether the receiver had an uncontested shot during the exchange. Continue through a middle catch, a pass out and a shot. If players only remember the first wing movement, repeat from the middle catch rather than always restarting at the top.
CoachAssist suggestion—not the source’s exact practice.
When: The center moves up to the ball.
Do this: The lower sides protect the space behind.
Then: Recover on the pass out without abandoning a receiver beneath the basket.
Source-backed summary; versions may differ.
When: The near lower defender closes out.
Do this: The center covers the near block.
Then: The high guard’s return-pass denial or help position depends on the selected call.
Source-backed summary; versions may differ.
Problem: Both defenders move, but neither is close enough to guard the catch.
Try this correction: Re-run the pass with a guided shooter allowed to raise the ball. Stop at that moment and have the arriving guard show that the handoff is actually ready.
Check: The call agrees with the positions; words alone do not make the exchange safe.
CoachAssist suggestion—not the source’s exact practice.
Problem: Several defenders follow the ball up and lose the player below them.
Try this correction: Put an observer on the baseline to identify the first uncovered receiver. Replay only the middle entry and the next pass.
Check: Check the lower pair before adding a faster outside reversal.
CoachAssist suggestion—not the source’s exact practice.
Changes: coverage.
When to use it: Additional trap rotations are written-only here; do not combine them into the base possession.

Source-backed summary; versions may differ.
Choose the level that matches what your players can do now. These steps work for boys and girls. Start simpler if players need more practice.
Set it up: An adult guides two passers and one defender over a short distance.
Add more when: Movement follows the actual pass, not a shouted direction.
CoachAssist suggestion—not the source’s exact practice.
CoachAssist wrote these teaching steps. They are not an exact copy of any coach’s practice plan.
His 2020 interview explains an aggressive 2-3 zone. This general 2-3 guide does not include all of Gallo’s rules.
The level selector changes the teaching steps above. It does not change these drills. Check the number of players, equipment and difficulty before using a drill.
Practices this scheme: The reviewed five-defender progression distinguishes a cross-court wing pass, where a lower defender approaches until a guard takes over, from a corner pass where the lower defender stays on the ball.
Distinguish defensive assignments on a cross-court pass to the wing from those on a cross-court pass to the corner.
7–21 players · 5–12 minutes · basketballs
Distinguish defensive assignments on a cross-court pass to the wing from those on a cross-court pass to the corner.
Seven players: five zone defenders and two wing passers, one ball. Rehearse the pass across the court from wing to wing first; adding a corner receiver requires an eighth player. Spare balls and waiting players stay outside the active routes.
Optional: within a short coach-chosen timed interval, count sound decisions, controlled catches or completed defensive possessions. Stop at the planned time or sooner; no required makes, winning streak or exercise penalty. Rotate roles and allow rest regardless of the score.
Practices this scheme: Rehearses one 2-3 variant covering the corner and short corner beside the paint along the baseline while protecting the basket. Agree on those assignments before combining them with a guard taking over a wing receiver from a lower defender.
The 2-3 back line rehearses a selected corner/short-corner rotation and rim protection.
8–12 players · 6–12 minutes · basketballs
The 2-3 back line rehearses a selected corner/short-corner rotation and rim protection.
Eight players: three back-line defenders, four offensive targets and one feeder, with one ball. Declare this variant’s corner, short-corner (baseline area just outside the lane) and basket-protection assignments before passing. Spare balls and waiting players stay outside the active routes.
Optional: within a short coach-chosen timed interval, count sound decisions, controlled catches or completed defensive possessions. Stop at the planned time or sooner; no required makes, winning streak or exercise penalty. Rotate roles and allow rest regardless of the score.
