Punch 12: Central Crash Ball with Twin Decoys

{{asset:header_image.png}}

Overview

This crash ball with decoy runners play is a reliable gain-line option from a central ruck. Its purpose is not simply to run a powerful player into contact. Two believable threats make the defence hesitate, then the inside centre hits the seam between them. Use it between the 15-metre channels when the defence is set but narrow and you have quick ruck ball.

The active unit is 9, 10, 6, 8, 12, 13 and 11, with three players already securing the ruck. Attack moves left to right. Win three-to-five metres, present cleanly, then use the compressed defence on the following phase.

Setup

Place a ruck on the 50-metre line and cone a 20-metre working channel. The 9 is one metre behind the ball. The 10 is five metres behind and two metres open from the ruck. The 12 begins seven metres outside 10 and one metre deeper. The 6 starts one metre inside 12, and 8 one metre outside. Both decoys begin four metres behind the gain line so they can accelerate onto it.

Set four defenders in a connected line, with D1 opposite 6 and D2 opposite 12. D3 and D4 cover 13 and 11. When the ruck is secure, 9 calls “Punch”. It tells 6 and 8 to run hard, 10 to stay square, and 12 to hit late. Decoys must be live runners, not blockers: they may fix a defender with their line and pace, but cannot deny a fair tackle line under Law 9.1

Step-by-Step Instructions

1. Set and scan (0.0 seconds). The previous carrier presents long. Three ruck workers arrive through the gate and make the ball visible. The 9 checks D1 and D2 are square, then calls “Punch” with one hand raised. If the line has already folded hard open-side, cancel with “Exit” and play wide.

2. Launch with depth (0.2–0.5 seconds). The 10 takes one small retreating step, then advances square. The 6 and 8 launch full pace on converging unders lines. The 6 aims at D1’s inside shoulder; 8 targets the space just inside D2. Their eyes stay beyond the line and they do not look back. The 12 delays half a beat with square shoulders.

3. Pass late and hit the seam (0.6–0.9 seconds). The 9 passes to 10 by 0.7 seconds. The 10 takes three square steps, shows the ball to 6, then passes flat in front of 12 only when D1 has committed to 6 or D2 has narrowed onto 8. The 12 catches at pace in two hands, adjusts to win the shoulder, and attacks between D1 and D2. Carry in two hands until the final step, then make legal contact low and drive through it.

4. Finish the collision (1.0–1.8 seconds). The 12 fights for one extra step and turns to present back towards 9. The nearest decoy, normally 6, reacts into the cleanout. The 8 scans for the poach threat before becoming the second cleaner. Do not over-commit both if 12 has won cleanly.

5. Reload (1.8–3.0 seconds). Support creates a stable ruck with the ball at the back. The 9 calls “quick” and delivers within three seconds. The 10 realigns six metres from the new ruck; 13 holds width, while 11 keeps touchline width or tracks in behind 13.

6. Attack the edge (3.0–4.0 seconds). If D1 and D2 compressed on the crash, 9 passes to 10 and 10 feeds 13. The 13 may take D3’s outside shoulder, put 11 away, or step inside a drifting D3. If the defence stayed wide and the seam remains, repeat the crash with 8 as carrier and 12 as a decoy.

Key Coaching Points

Coach the first receiver to be square before fast. A drifting 10 lets the defence slide and removes the decoys’ influence. Demand a late pass with soft hands so 12 receives moving forward rather than reaching behind their hips. The key visual cue is D1’s shoulders: once D1 turns inward to track 6, the seam is available.

The decoys must sell genuine intent through pace, body height and eyes. They should pass through the line, never stop in it. In contact, coach the carrier to protect the ball on the far side, keep a strong spine, and place it long. Support’s first job is speed through the gate, not a dramatic clear-out.

Common Mistakes

• 10 drifts early: D1 and D2 slide together. Rehearse a square three-step run before the pass.
• Decoys start shallow: They have no speed and are easy to ignore. Start four metres back and demand a hard, legal line.
• 12 goes too soon: The carrier reaches the line before the decoys. Reinforce the half-beat delay.
• Ball is slow after contact: The edge disappears if the ruck exceeds three seconds. Time the presentation and first two cleaners.

Variations & Progressions

For a tip variation, 10 gives short to 6, who can crash at D1 or tip out the back to 12; 8 remains the second decoy. Use it when defenders are reading the 10-to-12 pass. For an overs variation, 13 runs hard behind 12. If D3 bites on the crash, 12 can tip or pass after the line when the support picture is clean.

Progress from walk-through timing to passive defenders, then tackle-ready D1 and D2, then a live six-versus-six channel game. A score counts only if the first carry wins the gain line and the second phase is played within four seconds. Change the defensive picture so 9 and 10 learn to decide, not recite.

Age Adaptations

For under-12s, use touch or wrap tackle, one decoy and a 15-metre channel. Reward a pass made after the defender is fixed. For under-14s, add two decoys, controlled contact and a one-second presentation target. For under-16s and open age, add live jackal pressure and permit a blitz or drift. Apply the team’s approved tackle-height policy and player capability. In every version, stop play if a decoy crosses an opponent’s line without a genuine running line; legality and safety are non-negotiable.1
