Pocock could do it. Hooper is a bit firey but could do it, but I prefer him to focus on the game.
Of the backs, Giteau seems to me the only one with the combination of being close enough to the ref to be effective, and experienced enough for the job.
Is your confidence in the coaches, analysts and players within the Wallabies camp so low that you think they can't come up with strategies to manage the ref?
Well, I thought they could come up with strategies to deal with both the refs and the weather in the England series, and they couldn't do that. Bleating in the media "but we play running rugby!" is not a strategy.
In all the time Cheika has been at the helm, can anybody honestly say they've seen a single test where the Wallabies have mixed it up in their game plan? Or changed strategies at half-time when it's obvious things aren't working?
I can't really think of any.
