It was until the RWC when he re-injured his foot. McCaw did his best to mask the injury and play through the pain but Matt Todd hovered close to the squad and their trainings in case McCaw quit the tournament.
At times he struggled to walk as he hid the pain from everyone in the All Blacks except a select few. He was sure his foot was broken but avoided any x-ray confirmation.
McCaw supplemented his diet with painkillers mixed with willpower.
"If we know for sure it's broken, then it's going to be much more difficult for everyone around us to keep me on the field," he said in his book. "Because whatever the ramifications, I'm going to keep playing on it as long as I can stand up and do my job."
It got so bad, McCaw almost quit the semifinal win against the Wallabies when he felt another crack in his foot and intense pain. He was in agony making it up the tunnel at halftime.
McCaw hung on and led his men into the final. When the All Blacks won 8-7 McCaw doubled over in relief and sank to his haunches. His job was done.
"It's finished. I can stop. I don't have to do this anymore," he said.
