Erasmus goes into Saturday's Rugby Championship opener against Argentina in Buenos Aires with 13 changes from the Wales game and a squad carrying significant match-fitness deficits — but Kolisi's return from injury isn't what's keeping him up at night. After missing the entire Nations Championship phase, Kolisi starts at openside and is expected to play just over a half before Van Staden takes over. Erasmus is more concerned about Etzebeth and De Jager, both of whom have had minimal game time this year at any level — Dixon and Wiese are their planned second-half replacements, with the lineout-calling responsibilities of De Jager dictating that Wiese makes a direct swap rather than Dixon. The fitness picture extends further: Moodie, Hooker, Feinberg-Mngomezulu, and Pollard are all managing their way back, while Elrigh Louw and Cameron Hanekom haven't had enough game time to be fully settled. Erasmus is framing this one squarely as a grind — the target is a win, not a performance, with Argentina's sevens-heavy personnel and physical approach making that a realistic enough expectation.
