With the four-test 'Greatest Rivalry' series kicking off at Ellis Park on Saturday, Sean Fitzpatrick — who captained the only All Blacks side to win a series in South Africa — is under no illusions about what Rennie's team faces. His verdict is blunt: New Zealand must execute flawlessly across discipline, set-piece and preparation, because the Boks will punish any lapse. Fitzpatrick flags South Africa's defensive line speed, ball-carrying power and attacking threat as a multi-dimensional challenge, pushing back on any notion that the Boks will look to slow the game down. He's also reasonably satisfied with the Rennie transition and frames this extended tour — the first since 1996 — as invaluable World Cup preparation, provided the All Blacks can handle the pressure of chasing history in hostile territory.
