The Oita Stadium roof will be closed when the All Blacks play Canada tomorrow, but that isn't to say there won't be wet and difficult conditions as anyone who saw Scotland slide their way to victory over Manu Samoa at the enclosed Kobe Misake Stadium will attest.
That particular match, won 34-0 by Scotland and badly affected by the very high humidity inside the stadium, highlighted too the importance of being direct when necessary and adaptable, too. The Scots changed their game to suit the conditions whereas the Samoans couldn't or wouldn't.
All of which brings us to the All Blacks here and their approach against Canada, a nation ranked 22nd in the world they should beat comfortably without trying anything too out of the ordinary. It's here that Sonny Bill Williams may be especially prominent, with the big second-five starting outside playmaker Richie Mo'unga for the third time and able to provide momentum like few others.
Williams celebrated the start of his third World Cup when linking with No10 Mo'unga in playing 30 minutes off the bench during the win over the Boks in Yokohama. After starting alongside the little Crusader against the Boks in Wellington and Wallabies at Eden Park, the 1.94m Williams gets another chance to push his case and is likely to do so in the most physical way imaginable.
