The Springboks will manage player load carefully during the Rugby’s Greatest Rivalry Series, with coach Rassie Erasmus saying less-experienced players would be called on to support the older group. “We all believe they will be in the Greatest Rivalry squad,” the Springbok coach said on Tuesday. “I really believe it will be tougher than a World Cup pool. And normally after a World Cup pool, you struggle to find enough locks, enough loose forwards, enough flyhalves. “You don’t go to a World Cup without having two or three [additional] flyhalves on the radar.”
