Justin Marshall - former All Blacks halfback and now one of the world's best rugby commentators and analysts - joins Martin Devlin on It's Only Sport, to recap New Zealand's 47-5 win over Fiji in San Diego, while also looking ahead to the Rugby Championship. The All Blacks rounded out their July test window with a comfortable win over their Pacific neighbours, in a contest where coach Scott Robertson was able to trial fresh combinations and blood new caps. Marshall and Devlin discuss the match and how convincing - if at all - the All Blacks were, the greater challenge that Argentina will present, how former captain Sam Cane fits into the current side, and more.
