Laurie Mains is broadly impressed with what Dave Rennie has built — the style, the early Nations Championship results, and specific selections like Tupou Vaa'i at blindside — but his bigger concern is the cumulative load New Zealand's top players are carrying in 2026. After a gruelling Super Rugby season, the All Blacks face a Nations Championship campaign followed by the Greatest Rivalry tour of South Africa: URC franchise games plus three Tests against the Springboks, then a fourth in Baltimore in September. Mains's argument is blunt — there's a ceiling, mental as much as physical, to how many times elite players can genuinely peak in a season, and he thinks New Zealand are pushing past it. For Springbok supporters, the implication is pointed: if the All Blacks arrive in South Africa in August carrying heavy legs and a fatigued squad, the Boks may be facing a depleted version of Rennie's side rather than its best.
