The Springboks and All Blacks will both be targeting wins in the RGR series and next year's World Cup in Australia, but which is bigger? With the Springboks and All Blacks set to clash in four Tests over the coming weeks, it has to be asked whether winning Rugby’s Greatest Rivalry (RGR) series will be a bigger accomplishment than winning the World Cup in Australia next year? The two sides are currently ranked first and second in the world, and have won the last five straight World Cups between them, stretching back to 2007. RGR the prizeI thus believe that both teams, if given the option of choosing to win either the RGR series or next year’s World Cup, would choose to triumph in Rugby’s Greatest Rivalry. Of course, winning a third straight World Cup title in Australia next year would remain something very special.
