Cardinelli's argument is straightforward but the numbers behind it are striking: 26 of Rennie's 44-man squad — 59% — haven't set foot in South Africa during this World Cup cycle, and 17 haven't faced the Boks in the last four Tests. That's a significant experience gap heading into a four-Test series against a side that has won five of the last six meetings and holds more Test caps overall (1550 to 1270). The piece frames the three warm-up fixtures against the Stormers, Sharks and Bulls not merely as tune-ups but as a genuine acclimatisation window that Rennie can't afford to waste — particularly given the Bulls game on the Highveld comes just a week before Ellis Park. The added wrinkle is Savea being rested through the club matches, meaning Rennie's captain only integrates as the Test pressure peaks. With inevitable tour attrition likely to thin the squad before the series ends, Cardinelli argues the depth question will ultimately decide who wins — and right now the depth advantage sits firmly with the Boks.
