Schalk Burger's central argument is straightforward: the All Blacks' high-tempo attacking style is physically expensive, and four Tests in a month — two of them at altitude — will expose whatever depth gaps exist in Dave Rennie's squad. His contrasting point about the Springboks is that injury and rotation have, almost accidentally, produced a third layer of Test-ready forwards. He namechecks Dixon, Wiese and Hanekom as players who've already had game time this season, with Hanekom potentially filling the Kwagga Smith impact role off the bench. Burger also anticipates Erasmus rotating deliberately between Cape Town and Johannesburg given the altitude demands, and sees Baltimore as the likely series decider — a view Justin Marshall shares, with the All Blacks great openly saying reaching game four down 2-1 would feel like a platform rather than a crisis. The broader analytical tension here is whether the All Blacks sharpen as the series progresses — Burger thinks they will adapt after the first Test — but whether that adaptation comes fast enough to outpace the Boks' depth advantage.
