Former Springboks kicking guru Vlok Cilliers believes he's identified a weakness in the All Blacks that could cost them the Rugby World Cup: Beauden Barrett's goal kicking.
Barrett's ability off the tee has been under fire for the past couple of weeks after the No 10 kicked just two of six conversions in the All Blacks' 36-34 loss to the South African side in Wellington earlier this month.
Speaking to South Africa's Sport24, Cilliers acknowledged Barrett "is the world's best and most dangerous flyhalf, and out of hand can kick very smartly" however there was not a lot to be desired in his ability off the tee.
"Look, a lot of time in recent years the All Blacks have been outscoring teams by, say, five or six tries to two, so even if he kicks at somewhere around a modest 60 per cent success rate the All Blacks won't feel it too much on the scoreboard.
"What happened in Wellington ... it's not a fluke. There had already been stats available to show the danger of New Zealand losing through bad kicking.
