Dave Rennie is framing the South Africa tour as a genuine World Cup audition rather than routine Test prep, with the stated aim of identifying which fringe players are credible 2027 options. He's planning to trial the 6-2 bench split — something the All Blacks haven't touched since the Foster era's Twickenham hammering — giving the Bok franchises matches extra tactical significance. Scrum-half depth is being managed carefully: Ratima and Preston need the game time, so they carry the load in the provincial fixtures while Roigard is protected, with Carter's ability to cover nine being the enabler for the heavier forward bench. Mo'unga remains in the picture conditionally — one Canterbury appearance unlocks him as injury cover at 10. Most telling is Rennie's repositioning of Ioane: he's a winger in this setup, full stop, with his versatility a bonus rather than the point. For Springbok supporters, the piece maps exactly where the All Blacks see their depth gaps heading into 2027 — and where Rennie expects the South Africa environment to expose them.
