With the series locked at 1-1, this preview cuts to the two central tensions heading into Johannesburg. South Africa's scrum has dominated debate all series, but the more uncomfortable truth for Erasmus is that the All Blacks have scored nine tries to the Boks' four across the first two Tests — repeatedly finding space wide through slick first-phase attack. That edge-defence problem is the one South Africa genuinely needs to fix. The second tension is the bench: for the first time in a while, the Bomb Squad hasn't been the decisive factor, with New Zealand finishing stronger in both Tests. The piece also flags Amashukeli's appointment as a fascinating subplot — a Georgian referee who understands scrummaging culture, refereeing the most scrutinised set-piece battle in world rugby right now. Rennie holds his backline but reshuffles the tight five to address Cape Town's lineout woes, while Nché, Marx and Louw return to the Bok starting front row after their last-minute demotion to the bench last week. Rugby365 tips South Africa by three.
