Sean Fitzpatrick — the last All Blacks captain to win a series in South Africa, back in 1996 — argues that the Greatest Rivalry tour this August is the ideal World Cup dress rehearsal for New Zealand. His logic is straightforward: winning four consecutive Tests across a hostile South African environment demands exactly the squad depth and consistency a team needs to go deep at a World Cup. He's candid that the Nations Championship performances against France and Italy won't cut it against the Boks, but he's not writing off the All Blacks' chances either. On the Springbok side, Fitzpatrick is unambiguous — South Africa are the best team in the world, and the depth Erasmus has built is a core reason why. His one open question is whether the Boks can handle the pressure that comes with being number one.
