Murray Mexted's assessment of New Zealand's lock crisis cuts to the bone: after years of taking Retallick and Whitelock for granted, the All Blacks are still searching for a settled combination to replace them. Mexted draws a sharp contrast between Rennie's methodical, performance-first approach and Erasmus's broader squad-building mandate — framing Rennie's Darry-Vaa'i lock pairing for the Soweto Test as a calculated risk rather than a statement of intent. The core concern is structural: dropping Holland reduces New Zealand's lineout jumper count against a Springbok side with one of the game's best defensive lineouts, and Mexted's lineout maths is blunt — below 50% ball, the All Blacks probably lose. Whether Darry can translate his Lions game form into a Test against the world's best, at altitude in South Africa, is the unresolved question the piece hangs on.
