Sean Fitzpatrick — the last All Blacks captain to win a series in South Africa, back in 1996 — argues the Greatest Rivalry tour is the ideal World Cup dress rehearsal. His logic: winning four consecutive Tests across the series demands the same squad depth and consistency a World Cup requires, making the series not just a prestige contest but a genuine selection and preparation crucible. He's unambiguous about the current standings, calling the Springboks clearly the best team in the world and crediting Rassie's depth-building as a key reason why. His note of caution for the Boks: the pressure of defending that number-one status is its own challenge. For All Blacks fans, his message is cautiously optimistic — he acknowledges the Nations Championship performances won't be good enough against South Africa, but sees the series as a meaningful opportunity rather than a bridge too far.
