Erasmus is framing Saturday's Ellis Park opener as a grind precisely because he sees Rennie's All Blacks as a fundamentally different beast from Robertson's. His headline stat: New Zealand have roughly doubled their breakdown count and passing volume under Rennie compared to the Robertson era — a deliberate pivot away from the kick-heavy game that drew criticism after the last World Cup cycle. Erasmus's read is that New Zealand have publicly committed to a fast, high-tempo, ball-in-hand identity and can't credibly retreat from it now, which means the Boks know exactly what's coming. His preparation focus is breakdown pressure and handling New Zealand's pace and intensity, while acknowledging the Boks will need moments to impose their own attacking shape. He rates the two squads as closely matched on experience and recent minutes, which is why he won't call a winner — and neither, he suggests, will Rennie.
