Sir John Kirwan has offered a measured post-mortem on Leroy Carter's costly defensive night in the All Blacks' 29-24 loss to the Springboks, drawing on his own playing experience to contextualise the errors while stopping well short of excusing them. Carter was directly at fault for two Bok tries — a missed tackle on De Allende that set up Arendse, and a rushed, mistimed hit on Kriel that the centre punished with a fend-and-score — defensive lapses that cut sharply against Carter's productive attacking contributions in the same match. Kirwan's technical read is that Carter rushed both challenges rather than holding his shape, giving Kriel in particular all the time and options he needed. The broader picture Kirwan paints is of an All Blacks side that didn't lose on one play but on an accumulation of small errors — two missed tackles, scrum instability, and a maul they couldn't stop — leaving them 2-1 down in the series heading into the Baltimore finale. Worth reading for the granular technical breakdown of how Kriel's fend works and why it remains one of the harder defensive problems in the game.
