At 22 and approaching his sixth Test cap, Zachary Porthen is refreshingly clear-eyed about where he sits relative to Wilco Louw — and it's not false modesty. In a Rugby365 interview ahead of the Boks' clash against Argentina in Buenos Aires, Porthen describes Louw's scrummaging as 'mesmerising' and frames it as the benchmark he's still working toward, particularly after Louw's move to the Stormers will put them in the same environment next season. The piece also touches on Porthen's training habits — he sets specific improvement targets session by session — and how scrumming against the likes of Boan Venter in training has him confident for the Los Pumas test. Erasmus's public comparison of Porthen to Louw earlier this year adds context: the succession plan looks deliberate, and Porthen seems to understand exactly what's expected of him.
