Rassie Erasmus was able to make wholesale changes to South Africa’s starting front row shortly before kick-off against New Zealand, but the Springboks coach will not be permitted to repeat the tactic at the 2027 Rugby World Cup or under standard World Rugby regulations.
Erasmus surprised the All Blacks before last Saturday’s second Test in Cape Town by replacing his entire front row only an hour before the match began.
Gerhard Steenekamp, Deon Fourie and Thomas du Toit were promoted from the bench, taking the places of Ox Nche, Malcolm Marx and Wilco Louw. The original starting trio had been named on the Monday of the previous week.
The late reshuffle immediately attracted attention, but Erasmus had not breached the rules governing the current Greatest Rivalry Series. The competition’s regulations gave him the freedom to make the changes, and he has suggested he could use the same option again in either of the two remaining matches.
That opportunity will not be available in every competition.
New Zealand assistant coach Mike Blair acknowledged that the All Blacks had taken note of South Africa’s last-minute selection change, although he said it had not been allowed to interfere with their preparation.
“You take notice of it, but you take it with a pinch of salt as well,” Blair said.
“Listening to what he said after the second Test about how he changed the team around dependent on the weather, it shows that they’ve got the capability of doing that.
“But we’re not going to spend huge amounts of time planning for a certain individual in a certain position when we’re pretty aware that that can change right up until kick-off.”
The element of uncertainty was arguably the main advantage South Africa gained. New Zealand had prepared for the starting XV announced in advance, only to discover that the line-up had changed shortly before the opening whistle.
Why the tactic will not work at the 2027 World Cup
The Greatest Rivalry Series has its own rules, which differ from the usual World Rugby regulations governing international matches.
Under those standard regulations, teams must submit their starting XV and replacements within specified deadlines before kick-off. Coaches can make late changes in certain circumstances, particularly when injuries or other approved situations occur, but they cannot simply replace an entire front row for tactical reasons shortly before a match.
Those restrictions will apply at major events and competitions including the 2027 Rugby World Cup in Australia, the Rugby Championship and the Nations Championship.
Erasmus therefore identified a gap in the rules rather than breaking them. The regulations for the Greatest Rivalry Series gave him considerably greater room to alter his selection, and he took advantage of it.
The move has nevertheless prompted a wider discussion about whether rugby’s traditional approach to team announcements remains appropriate.
Opponents naturally gain little from being confronted with an unexpected line-up, while some South Africa supporters saw the decision as another example of Erasmus’ willingness to think differently.
Rugby teams are generally required to confirm their selections well before kick-off, allowing opponents to study specific players and combinations. It also forces coaches to finalise decisions days before a match, even when conditions may change.
Football teams, by comparison, usually announce their starting line-ups about 90 minutes before kick-off. In cricket, the teams are often confirmed shortly before play, frequently at the toss.
For now, Erasmus’ front-row switch remains legal within the Greatest Rivalry Series. But unless the regulations change, the same tactical surprise will not be available to him at the 2027 Rugby World Cup, the Rugby Championship or the Nations Championship.
