Disrupting the set piece: Patterns in defensive lineout strategies in the 2022/23 English championship

This study aimed to examine defensive lineout strategies during the 2022/23 English Championship rugby union competition, accounting for contextual and tactical factors associated with successful lineout disruption and variation across teams. All regular-season fixtures involving the top six teams were analysed (n = 1876 defended lineouts across 97 matches). Performance indicators were derived from literature and expert consultation, operationally defined, and coded using Hudl SportsCode. Lineout outcomes were examined for associations against pre-, during and post-line phase variables using Chi-square tests and Cramer's V (p < .05). Defensive teams disrupted 18.4% of lineouts, with Coventry Rugby achieving the highest disruption rate (22.4%). Associations were observed for pitch zone (V = .186), formation (V = .091), contesting status (V = 0.164), contesting zone (V = 0.348), intended target (V = 0.164) and lifting/pod structure (V = 0.299). Disruption tended to be greatest when contests occurred in front of the attacking jumper and when two lifters supported the defensive jumper. Defensive effectiveness appeared to be associated with contextual factors and resource allocation. Aggressive contesting positions and optimal lifting support were associated with disruption potential. Findings provide provisional, evidence-informed insights that may assist coaches in refining defensive systems and improving turnover opportunities.
