With RWC 2027 now close enough to see on the horizon, Angus Opperman identifies five players Erasmus should be tracking as bolters for Australia. The piece is anchored around the weekend's Wales Test, where several of these names made their cases in real time. Quan Horn de Villiers gets the strongest endorsement — compared to Heinrich Brüssow in his poaching ability, he's framed as the ideal impact loose forward off the bench behind Kolisi. Sacha Feinberg-Mngomezulu... wait — the five are: Louw backup Carlu Sadie (now the cornerstone of Champions Cup holders Bordeaux-Bègles), whose scrum power fits the Bok mould perfectly; lock Ruan Norton, whose versatility to play loose forward echoes Pieter-Steph du Toit and addresses a genuine depth problem in the second row; fellow lock Reinhardt van Heerden, who backed up his debut with 17 tackles and five lineout wins against Wales and is seen as the natural Kleyn replacement; and young outside back Sacha Williams, whose debut drew praise despite some rawness, with his wing-fullback versatility putting him in contention for that third outside back spot behind Kolbe and Arendse. The broader thread tying the selections together is Bok squad balance — age profile at lock, tighthead cover with Malherbe fading, and impact bench options in the loose forwards.
