The spine of any rugby team, the No 8, halfback and five eighths, is usually a key to their results.
Those men are the computers who run the game, they are the minds who sniff the game and feel its pulse. Their instincts about how to change a plan, alter the pace and rhythm of their tactics or persevere with their strategies, are crucial to international outcomes.
For the All Blacks last night, that group was Kieran Read, Aaron Smith and Daniel Carter, while the Wallabies fronted with Scott Higginbotham, Will Genia and Berrick Barnes.
There's no question Genia is the best halfback in world rugby, a gifted ball player and decision-maker whose influence runs heavily though the Wallabies. He waited until after the first quarter to have a snipe and made a sizzling incision towards the All Black line.
The Wallabies won a penalty but strangely ignored the shot at goal in favour of seeking a try and succeeded only in conceding a penalty themselves.
