In a Squidge Rugby interview, Mtawarira traces the precise moment South Africa's scrum shifted from 'wanting ascendancy' to actively hunting penalties on every single set-piece: Matthew Proudfoot's arrival in 2018. Before that, Beast argues, the Boks had the physical culture and occasional brilliance — the 2009 Lions series being the standout — but lacked the sustained, ruthless mindset Proudfoot instilled. He credits Daan Human for building on those foundations, but the philosophical pivot was Proudfoot's. Beast also points to the internal competition generated by the Bomb Squad structure as the engine behind the scrum's consistency — the training intensity between Marx and Mbonambi, Kitshoff and himself, Koch and Malherbe was so fierce that Test matches felt comparatively easy. With Porthen, Sadie and others coming through, he sees no reason that edge dulls anytime soon.
