Planet Rugby's post-series winners-and-losers breakdown argues that the Rugby's Greatest Rivalry concept, for all the criticism it drew from Argentina and Australia, delivered beyond expectations — and in doing so set a benchmark that the Rugby Championship will struggle to match. On the field, Malcolm Marx is identified as the standout player across all four Tests, his set-piece dominance and breakdown work leaving New Zealand with no answers, while Kolisi's return after the Ellis Park defeat is framed as the turning point that reshaped the series. Damian de Allende edges Ardie Savea for recognition in the winners column — his containment of Jordie Barrett after Test 1 seen as quietly decisive. The piece is also direct about the losers: Sacha Feinberg-Mngomezulu is named as a disappointment, not out of form but timing, returning from injury before he was ready and never finding his rhythm. Leroy Carter's two defensive lapses in Soweto are pinpointed as the moments that swung the series. The Baltimore communication debacle gets its own entry — Steve Hansen's fury quoted at length — as an embarrassment that undermined what should have been a showcase occasion. The most pointed analytical conclusion, however, concerns New Zealand's leadership depth. With Savea fit, the All Blacks look formidable; without him, the piece argues they look rudderless in a way the Boks simply don't, given the bench of leaders Erasmus can draw on — a gap flagged as a genuine World Cup concern with twelve months to address it.
