With Ellis Park set to host the opening Test of Rugby's Greatest Rivalry, this piece revisits five of the most visceral clashes in over a century of Springbok-All Black history. The selection ranges from the bone-rattling 1921 series opener — which effectively set the template for the rivalry's physicality — through to the infamous 1981 'Barbed Wire' Test at Eden Park, where a Cessna buzzing the stadium was arguably less chaotic than Clive Norling's refereeing in nine minutes of added time. The 1970 Kings Park encounter gets particular attention for its outright brutality, with Piston van Wyk leaving the field bloodied after a breakdown incident. The 2015 World Cup semifinal is framed as the rivalry's modern-era benchmark — 116 Springbok tackles, Francois Louw's 16-stitch facial wound, and a Richie McCaw elbow that never got properly punished. But the centrepiece may be the 1956 series, built around the recall of Kevin Skinner — New Zealand heavyweight boxing champion — with what amounted to an explicit mandate to 'sort out' Jaap Bekker and Chris Koch. Two punches later, the Springbok scrum had psychologically collapsed and New Zealand had won the series 3-1. It's a worthwhile read ahead of Saturday's Test for anyone wanting historical context behind the fixture's unique intensity.
