Kolisi has been effusive about the three U20 callups — Jaco Williams, Riley Norton and Vusi Moyo — who Erasmus has pulled into the Nations Champions Cup squad ahead of the Junior World Championship. What stands out from his comments isn't just the praise, but the reason for it: Kolisi sees their fearlessness and high-intensity training as a genuine stimulus for the senior group, not just a development exercise. Norton hasn't played a single minute for his franchise, yet the Bok coaching staff were sufficiently impressed to include him. Kolisi also frames the integration as a leadership responsibility for the experienced players — the knowledge transfer happening off the field, in hotels and corridors, is as deliberate as anything on it.

Kolisi's verdict on the three Junior Bok callups reveals how Erasmus is using their fearlessness as a training catalyst for the senior squad — and why the knowledge-transfer burden now sits squarely with the experienced players.
