defense
One published 2-1-2 version starts the center near the free-throw line, between two guards farther out and two defenders nearer the basket. Some programs instead use 2-1-2 and 2-3 interchangeably.
This uses the Basketball For Coaches version: X3 starts in the middle, moves lower on a corner pass, and guards a catch near the free-throw line. The label alone does not settle these rules.
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.

2 passes to 3. X5 takes the corner. X3 and X4 move lower; X1 and X2 cover above them.

Use Previous and Next beside the court, or choose a numbered step. Arrows on the court show where players or the ball move. CoachAssist drew this example; it does not show every way to run the scheme.
This is the Basketball For Coaches 2-1-2 version, translated into our roles. The middle defender moves with the situation. A stationary-middle “Buzz” version is a different choice.
X1 and X2 start high, X3 works the middle, and X4 and X5 start lower. The source labels our middle role X5. On a corner pass, X3 moves toward the near block; the near lower defender takes the ball and the opposite lower defender protects behind.
Source-backed summary; versions may differ.
Place a marker at the middle starting spot, then remove it once players know the formation. Run a corner catch and a middle catch in either order. Ask X3 what changed rather than where the marker used to be. Have the other four describe the space X3 left. Continue until the offense takes a controlled shot, so the group also practices finding rebounders after its middle defender has moved.
CoachAssist suggestion—not the source’s exact practice.
When: X3 guards this catch alone.
Do this: The upper pair finds outside receivers; the lower pair protects beneath.
Then: Do not import a two-defender high-post trap from another zone.
Source-backed summary; versions may differ.
When: The pass starts on the wing or in the corner.
Do this: A wing-origin skip calls the far lower defender first; a corner-origin skip calls the far upper defender.
Then: The pass origin matters.
Source-backed summary; versions may differ.
Problem: The corner catch pulls a lower defender away while the near block is uncovered.
Try this correction: Replay with only the ball, near block receiver and lower pair. Ask X3 to identify the newly exposed space before increasing the number of attackers.
Check: The movement answers a visible threat instead of following a cone.
CoachAssist suggestion—not the source’s exact practice.
Problem: Two defenders approach the catch, or both wait for the other.
Try this correction: Have an observer call the starting location of each skip. Compare the two situations slowly before mixing them randomly.
Check: Players name the incoming defender before the pass is released.
CoachAssist suggestion—not the source’s exact practice.
Changes: coverage, setup.
When to use it: Buzz and the complete short-corner trap are written-only; use the displayed moving-middle rules for these examples.

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: Use an adult passer, one receiver and one guided defender near the basket.
Add more when: The defender follows the actual receiver rather than a fixed floor mark.

CoachAssist wrote these teaching steps. They are not an exact copy of any coach’s practice plan.
We have not confirmed a specific coach or team using this version. Teams may use the same name for different plays.
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.
Builds a skill used in this scheme: Practices zone rebounding only. It does not assume 2-1-2 is a synonym for 2-3 or decide the center’s assignment near the free-throw line.
Two defenders communicate which of five numbered attackers to account for on a shot.

Two defenders communicate which of five numbered attackers to account for on a shot.
Seven players: five numbered perimeter attackers and two lane defenders, plus a coach shooter. Begin with a held or gently tossed ball and controlled, non-contact positioning before live rebounds. 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.
