Box 2: Under-Basket Inbound Play

Equipment Needed

2 basketballs
Half-court or full FIBA court
10 reversible pinnies
4 floor cones
Whistle
Whiteboard or clipboard
Visible five-count timer

Overview

This Box BLOB (baseline out-of-bounds) is a dependable under-the-basket inbound package for a coach who wants a simple first look, a built-in counter, and a safe way to keep possession if the defense takes away the rim. The action uses a compact four-player box in the lane, then creates separation through a decoy cross-flash and a lift-and-screen for the shooting guard. Your primary finish is a catch at the rim by 2 (shooting guard); the counter is 5 (center) slipping when the defense switches or top-locks the screen. The point guard is deliberately held as the safety valve, not asked to crowd the scoring action.

Use it after a dead ball on the attacking endline, especially after a timeout or any baseline throw-in near the basket. A FIBA court is 28 m x 15 m, and the thrower-in must release the ball within five seconds, so train a decisive early trigger.1

Call: “Box 2.” The number tells the group that 2 is the first live scoring option. If the ball cannot enter cleanly, call “Green” and flow directly to your half-court offense through 1.

Setup

Tactical diagram

Use one basket and the attacking half-court. Put a coach or manager on the baseline with a whistle and visible five-count. In the teaching phase, use four cones at the elbows and low blocks; remove them once players own the landmarks. Install with five attackers, then add five defenders.

Player Starting location Job on the call
3 – SF / inbounder Out of bounds, centred under the rim, 0.6 m behind the endline Deliver the ball, then enter as a weak-side spacer.
1 – PG Weak-side elbow, about 5.8 m from the endline Clear to the top as the safety receiver and organizer.
2 – SG Strong-side elbow, one step outside the lane line Set up the defender, then curl to the rim as the primary option.
4 – PF Weak-side low block, 1 m above the endline Cross-flash as a decoy, then seal the smaller defender.
5 – C Strong-side low block, 1 m above the endline Lift into a legal screen for 2; slip if the defense switches.

Keep the box compact but do not let defenders guard two cutters. Start roughly 0.6 m inside the lane line and 1 m above the endline or free-throw line. The inbounder holds a balanced stance, sees the rim first, then the cutter, then safety.

Step-by-Step Instructions

Tactical diagram

  1. Call, match up, and trigger. Start in the box. 3 shows the ball, calls “Box 2,” and waits until every offensive player is still. On the referee’s hand signal or the coach’s cue, 3 gives a sharp ball slap. Treat the slap as time zero: the first cut starts immediately, with the ball normally delivered by count three or four, never at the edge of the five-count.

  2. Clear the safety lane. At the slap, 1 retreats through the nail to the top, roughly 6.75 m from the basket. 1 stays visible to 3 and out of the scoring pass line.

  3. Create the decoy. 4 sprints from the weak-side low block across the lane to the strong-side block. The cut ends in a two-foot seal. 3 reads 4 only if the defender trails; otherwise the flash pulls help and hides the screen action.

  4. Build the screen. As 4 clears, 5 lifts from the strong-side low block to a point just below the strong-side elbow. 5 arrives first with a wide base and chest to the sideline. The screen is stationary before 2 arrives; 5 gives a tight route without moving into the defender.

  5. Win the primary cut. 2 takes a short V-cut toward the strong-side wing to move their defender, plants the outside foot, then cuts shoulder-to-hip off 5’s screen. 2 curls downhill through the lane and presents a target hand above the waist at the front of the rim. The cut must arrive about 1.5–2.0 seconds after the ball slap. 3 steps into a firm two-hand chest pass or short bounce pass; the pass leads 2 away from the defender and into a one-step finish.

  6. Read the counter, then protect possession. If 2’s defender trails, switch, or overplays the curl, 5 immediately slips to open space at the strong-side elbow or short corner. 3’s read order is 2 at the rim, 5 on the slip, then 1 at the top. If neither inside look is clean by count four, 3 delivers to 1. After any inbound, 3 enters to the weak-side corner and the team flows into its normal spacing. Do not force a window that is no longer there.

Key Coaching Points

Tactical diagram

Teaching cue What the coach should demand
“The slap starts the race.” Every movement is tied to one audible trigger. Late cuts let defenders jam the lane.
“Screen is early; cutter is violent.” 5 arrives and becomes stationary before 2 turns the corner; 2 changes speed and cuts tight enough to brush the screener.
“Show the target late.” 2 does not wave for the ball from the elbow. Show a hand only as the cut reaches the finishing window.
“Pass to space, not to a player.” 3 throws to the rim-side shoulder of 2, away from the trailing defender.
“Seal, then finish.” 4 completes the decoy with contact and a two-foot seal; do not float through the paint.
“Safety is a success.” A clean pass to 1 and organized flow is a winning possession when the rim is taken away.

Common Mistakes and Immediate Corrections

Tactical diagram

If 2 rounds the curl, use a cone at the screen hip and require a brush cut. If 5 moves, freeze the rep: 5 must arrive, balance, and wait before 2 turns the corner.

Correct 3 for staring at 2: use the snapshot order 4, 2, 5, 1. Keep 1 at the top; drifting into the lane removes the safety pass and clogs the rim.

Variations and Progressions

Tactical diagram

Variation 1 – Lob 4. Against a smaller switch-heavy unit, turn 4’s cross-flash into a high catch at the rim. Use touch passes and reserve it for an explosive 4.

Variation 2 – Screen-the-screener. If opponents deny 2’s curl, 4 reverses to screen 5 into the weak-side elbow for a 3–5 m jumper. Add it only after the primary action is sharp.

Progression – Live reads. Start against guided man-to-man, then add switches, top-locking, and a compact 2–3 zone. Against zone, 4 parks in the short corner, 5 screens the middle defender, and 2 flashes into the seam. Grade timing, legal screening, read order, and shot quality.

Age Adaptations

Tactical diagram

For Under 8 and Under 10, use only 3, 2, and 5: 5 stands as a stationary guide screen, 2 cuts to the rim, and 3 passes. Keep defenders passive until players can identify the baseline, paint, and target hand. For Under 12, add 1 as safety and 4 as the decoy, but permit one clear verbal cue from the coach at the ball slap.

For Under 14 and Under 16, use a live defense and require a switch-versus-trail read. At open/advanced level, use hand signals to alter the read order and chart conversion by option. Every level needs a sharp trigger, legal screen, decisive cut, and outlet.
