Gavin Rich's Championship wrap argues that South Africa's real advantage in the Nations Championship isn't just the log position — it's the margin by which Erasmus is outpacing rival coaches in squad-building ahead of the 2027 World Cup. The numbers are stark: across two matches the Boks have used 39 players in their match-day squads and fielded 25 different starters, compared to England's 26 players and 17 starters, and New Zealand's 31 and 19. Rich frames Borthwick's near-unchanged selection against Fiji as a symptom of a coach under pressure who can't afford Erasmus's experimental mindset — and contrasts it with Erasmus sending Pollard to centre and Horn to flyhalf against Scotland while still winning by 14 points with a reshuffled second half. The piece also notes that France are the only other side rotating meaningfully, making them the most credible RWC rival, while Ireland's log-leading two wins have come without convincing performances. The broader argument is that Erasmus is using the Nations Championship as deliberate World Cup rehearsal, and the gap in squad development between the Boks and the rest is already significant.
