Attack shape: 1‑3‑3‑1
The dominant Northern Hemisphere attack shape. Pods of forwards either side of the breakdown (the "3"s), with an outside-half +1 player at the front and a fullback / second receiver at the back. Predictable on paper, but the value is in the options — every forward pod can crash, tip-on, or pull-back to a wider runner.
Counter: what kills the 1-3-3-1 is a fast linespeed defence that arrives before the pod gets its second pass off, plus aggressive jackals at the breakdown to force forward bodies into rucks.
