Continuing on the positivity theme, this is a very good squad, and apart from the schemozzle against New Zealand, we've had an excellent year.
In terms of our RWC preparation, perhaps even the loss to the Kiwis wasn't such a bad thing. It will certainly have shaken out any possible complacency.
It'll be interesting to know what Cheika's thinking is on the two hooker question, because he does think, and thinks innovatively, about tactics. I very much doubt it's to square up the sides for practice sessions.
The selection of McMahon suggests that whatever happens, we're playing the Pooper game plan. That's good. It's a point of difference versus all the other teams. Taking on England (for example) at an attritional game, in England, in English conditions, would simply mean we lose.
