Dan Biggar's analytical take on the Rennie-era All Blacks is worth reading closely from a Springbok perspective. His core argument is that Rennie has engineered a wholesale identity shift — from Robertson's territory-heavy, kick-metric-driven game plan to a possession-based, multi-playmaker system that now leads the Nations Championship in carries and passes per game. Biggar draws explicit comparisons to the Henry/Hansen golden era, pointing to Ruben Love, Damian McKenzie, and Jordie Barrett as the multiple playmakers enabling rapid ball movement into wide channels, while Cam Roigard's near-abandonment of the box kick signals a structural commitment to keeping ball in hand.
The Springbok dimension is sharpest in the error-rate detail: the All Blacks were leaky against France in round one but tightened dramatically against Ireland, suggesting the system is bedding in quickly. Biggar's numbers — an extra 90 carries and 100 passes per game compared to Robertson's tenure — give concrete shape to what the Boks will face if these two meet deep in the Nations Championship. Given where the standings sit, that encounter looks increasingly likely.
