Victor Matfield's bold claim that the current Springboks are the greatest South African side ever assembled gets its first real examination this weekend as a four-test series against the All Blacks kicks off in Johannesburg. The historical weight is significant: between them, these two sides have claimed seven of the ten Rugby World Cups and the Rugby Championship has been their private competition for decades. Erasmus has gone with Feinberg-Mngomezulu at flyhalf — the same call that worked against the All Blacks last year — leaving Pollard off the squad entirely and Libbok on the bench. Kolisi is still managing a hamstring injury, so Du Toit leads. New Zealand, rebuilding under new coach Dave Rennie after Robertson's sacking, make just one change from their Nations Championship win over Ireland, with Holland coming in at lock. The series — marketed as the 'Greatest Rivalry' — runs across four consecutive weekends, with the finale in Baltimore.
