Dave Rennie has acknowledged Erasmus as a genuine innovator who will bring tactical surprises to the Greatest Rivalry series, but insists the All Blacks aren't arriving as passive recipients — they've got their own plans. Rennie's respect for what Erasmus has built is clear, though his tone is competitive rather than deferential. With several All Blacks players having limited or no experience of playing in South Africa since the franchises moved north, Rennie sees the three warm-up matches against the Stormers, Sharks, and Bulls as essential acclimatisation and selection pressure — altitude, hostile crowds, time zones, and all. The broader subtext is a World Cup stocktake: this tour is effectively a stress test of where the All Blacks genuinely sit against the benchmark the Boks have set over the past two World Cup cycles.
