With 13 changes from the side that beat Wales, Erasmus has used the Buenos Aires Test as a form-and-fitness exercise ahead of the All Blacks series. The headline story is Sacha Feinberg-Mngomezulu's return at flyhalf — his first action since the ankle injury sustained in the URC play-offs — and how he clicks with Reinach in a half-back pairing that could define the Greatest Rivalry Tests. Kolisi's comeback at openside, despite the Paul de Villiers noise during his absence, is treated as settled business after Erasmus's unambiguous endorsement. The Etzebeth–De Jager lock pairing is flagged as the biggest structural boost: both missed the Nations Championship through injury, and their fitness changes the Boks' second-row picture significantly. The piece also spotlights the Hanekom vs Jasper Wiese number-eight contest as live, and identifies Quan Horn, Herschel Jantjies and Wilco Louw as the unlucky trio squeezed out of a 26-man travelling squad — each with a reasonable grievance. Worth reading if you want a player-by-player breakdown of who's staking a Rugby Championship claim this weekend.
