Watch any amateur touch rugby set and the same three mistakes repeat. None of them are about pace or fitness. They're about decisions. Fix the three and your scoring rate doubles.
Error 1: The first runner takes contact
The middle takes the dive ball, sees no immediate gap, and runs into the touch. Set killed at touch one. Rule: if the gap isn't a clear hole, the first runner passes laterally to the link before contact. Always. The dive line is for opening space, not for being touched.
Error 2: Late ball to the wing
By touch four the ball has moved sideways with no penetration, then it's flung at the wing on touch five and they're cornered with the sideline two metres away. Rule: the wing's ball arrives by touch three, not five. If it's late, the wing has no room and the set dies.
Error 3: No support runner inside the ball-carrier
The link makes a half-break, has no inside support, takes the touch alone. The defending team resets cleanly. Rule: the player who passed must follow inside the ball-carrier — never trail behind. Inside support is what turns half-breaks into tries.
Drill it in 10 minutes
5-on-4 attack, defence cannot drift inward. The attack must complete a six-touch set scoring under three conditions: (a) first runner never takes the touch, (b) wing's ball arrives by touch three, (c) inside support runs at every pass. Twenty sets. The pattern locks in.
