The sharpest tactical thread in this third-test preview centres on what the Boks need to do differently at altitude. Jean de Villiers argued that with Damian Willemse out and Cheslin Kolbe moving to fullback, the backfield combinations are unsettled for a third consecutive week — and that the real vulnerability lies in defence, particularly the Boks' stopping power in the 22. He and Scala Burger both made the case that South Africa's defensive shape after winning breakdown contests has been poor, and that if the Boks are to win, the mentality needs to be 'go score 40 points.' On Siya Kolisi's return, the panel drew an explicit parallel with Richie McCaw — arguing that like McCaw, Siya's presence settles the team beyond what his individual minutes on the field account for, even if he's unlikely to go beyond 45-50 minutes again. Dave Rennie's scrum-walking complaint was largely dismissed as referee-targeting through the media, with de Villiers suggesting it was more about separating Ox Nché from the hooker than any legitimate procedural concern.
