Schalk Burger's case is straightforward: France and Ireland never properly engaged New Zealand in the kicking battle, meaning the aerial contest that hurt the All Blacks in Wellington last year remains an open wound heading into the four-Test series. Burger expects the Boks to target exactly that, backing Erasmus's side to apply serious pressure in the first two Tests before Rennie's men find their feet. Hanyani Shimange adds the set-piece dimension — scrums, mauls and lineouts haven't been stress-tested either, and that's where South Africa's structural advantage should tell. The flip side gets attention too: Rennie's more expansive approach could push the Bok defensive system harder than anything they faced in the Nations Championship, with Burger flagging tackle volume and sustained line-speed intensity as the real examination for this Springbok side.
