Dave Rennie has effectively flagged that the All Blacks' Greatest Rivalry tour is a depth audit rather than a performance showcase — and he's openly borrowing from Rassie's 2018 rebuild methodology to do it. After a patchy but ultimately comfortable win over the Stormers, Rennie confirmed wholesale changes for the Sharks match, with further rotation against the Bulls before the first Test. The goal is straightforward: stress-test the squad depth and identify his best Test lineup under competitive conditions. Rennie's Stormers debrief flagged tactical imbalances — particularly poor decision-making under pressure at 13 men — but he was encouraged by the composure of debutants and the fact that most Friday starters had minimal minutes in the Nations Championship series. For Bok fans, the piece is useful context on how Rennie views this tour window and what it signals about All Black preparation heading into the Test series.
