Jan de Koning's argument is straightforward but well-supported: the tactical innovations and win streaks are the headline, but Erasmus's true edge is an unprecedented squad depth that makes injuries functionally irrelevant. The England game is the exhibit — with Kolisi and Etzebeth absent, and eight frontline locks unavailable, the Boks still won 45-21, shifted Du Toit to lock without a physicality drop, and averaged 27 years old across the matchday squad after late changes. Against Scotland this weekend, that versatility continues, with Dixon, Tshituka and Louw all capable of covering both the back row and second row. De Koning's broader claim is that Erasmus has now built a system deep enough to field three competitive international teams simultaneously — something only France comes close to matching in terms of raw volume, though without the same tactical cohesion. The piece frames this not just as a current strength but as deliberate infrastructure for sustained dominance through 2031.
