The Springboks' experimental halfback pairing of Grant Williams and Sacha Feinberg-Mngomezulu unravelled spectacularly in Saturday's 33-16 defeat to New Zealand at Ellis Park, with the All Blacks ruthlessly exploiting a mismatch that had troubled South Africa before.
Williams, selected despite being unsettled by the same opposition at Eden Park last year, was targeted throughout the contest. All five New Zealand tries came against the scrumhalf, including four where the visitors identified him as the defensive closer on the edge and one from a charged-down box kick by Fabian Holland. The pattern was unmistakable: New Zealand had a recipe that worked, and they executed it with clinical precision.
Former All Blacks hooker James Parsons described the Williams-Feinberg-Mngomezulu selection as a "big gamble" that did not pay off. The pair had started together just once at Test level before Saturday, and the lack of cohesion showed as they lost control in the latter stages. "Before the game I mentioned that the Williams and Feinberg-Mngomezulu selection was interesting because they had only played once together and, in such a big game, I felt that was a big gamble," Parsons said.
All Blacks' defensive blueprint
New Zealand's defensive system played a significant role in the Springboks' struggles. By creating time in the tackle and holding up the ball carrier, the All Blacks prevented South Africa from generating quick ball to capitalise on their powerful carries. That bought crucial seconds for the defensive line to realign and bring line speed, a tactic Parsons identified as part of rugby's "new trend" in defence.
"You've also got to credit the defence. It has really improved on this tour, and you can only force errors by putting defensive pressure, and that's what the All Blacks did," Parsons said. The visitors' tackle percentage reflected their discipline, with the defensive structure forcing the Springboks into uncharacteristic errors.
The mismatch on the edge proved decisive. In the Springbok system, the No.9 acts as the closer, the last man to shut down play. Faf de Klerk excelled in that role with dominant contact on outside backs, but Williams lacks the same physicality. New Zealand exploited the size differential repeatedly, with Cam Roigard targeting the Jordan-versus-Williams matchup on the try line and firing a flat cutout pass for the winger to crash over.
Erasmus responds with experience
Erasmus has moved swiftly to address the issue, recalling Cobus Reinach and Handre Pollard for the second Test. The changes signal a return to experience and a more traditional halfback structure, with Reinach's sharper service and Pollard's game management offering greater control. Whether the shift steadies the ship or whether the All Blacks have exposed a deeper vulnerability in South Africa's selection philosophy will be answered in the coming days.
