He might decide, despite Carter's "red-flag" status, that the Crusader is still more reliable on a consistent basis than Cruden. He might have noticed that when the Wallabies made their spirited semi-comeback midway through the second half, Cruden made a questionable defensive decision when Michael Hooper scored, that exposed Aaron Smith and Richie McCaw.
But hell, it was a minor smudge on a glittering night. It is easy to forget that when the All Blacks played the Wallabies on this Fortress in the semifinals of the 2011 World Cup, Cruden was identified as the All Blacks weak link. It seems laughable now.
It should be noted, too, that Beauden Barrett made more than a cameo and spent some time at first receiver, where he looked test-match comfortable. He might not be trusted as much as the other two - he is yet to start a test at No 10 - but he's done enough to enter the conversation.
It's a conversation that, for the next few days at least, should be dominated by Cruden.
