Nick Mallett's read on the Rugby's Greatest Rivalry series is that both sides came away better informed. For the Springboks, the two-Test comeback after a poor opener gave Erasmus confirmation that the older, experienced core of the squad still has the legs and the leadership to perform when it matters — with the World Cup a year away, that's a significant finding. But Mallett doesn't sugarcoat it: the All Blacks scored 13 tries to South Africa's eight across the series, and he believes New Zealand identified a way to move around the Bok defence — a vulnerability Erasmus will need to address. On the New Zealand side, Mallett sees a squad that absorbed serious South African physicality without several key players, and views Barrett, Williams and others yet to return from injury as significant depth still to reintegrate ahead of the World Cup.
