South Africa head to Baltimore with the series wrapped up in all but name, but this piece argues the fourth test carries outsized importance precisely because of what it can reveal about World Cup readiness. The Bok power game — scrum and driving maul — proved decisive across tests two and three, and Rennie had no complaints about the penalty count after staying conspicuously quiet on the scrum this time around. The defensive concerns are real though: 13 tries conceded across three tests, with Erasmus himself flagging that Flannery won't be happy. Minor adjustments were visible — the backs holding slightly deeper to plug outside leaks — but there's work still to do, and the coaching staff knows it.
The Baltimore test now becomes a squad audit as much as a contest. Rotations are expected, and those selection calls will give the clearest picture yet of the depth behind the first-choice XV with the World Cup a year away. Kolisi's post-match assessment is telling: he doesn't think the last two performances were their best rugby, believes they left opportunities on the table, and sees room to improve on both sides of the ball. For Bok supporters wondering how wide the gap is between this squad's ceiling and its current output, the full piece is worth the read.
