In rugby, the term "7/1 split" refers to the composition of a teams bench, which consists of eight substitutes that can replace an on-field team-mate. The 7/1 split means that a team has seven forwards and one back on the bench. This strategy was first used by the South African rugby team in a warm-up game against New Zealand and was later used in their Rugby World Cup match against Ireland. The split is designed to give the team more options in the forwards, who are typically involved in the physical aspects of the game, and to provide more flexibility in the event of injuries or tactical changes.
