The expectation is that the Scots will start the game with a hiss and a roar and try to play wide and fast.
The Scots are a bit new to this pass and run malarkey and the All Blacks are hopeful that if they can apply maximum pressure at the breakdown, they may profit greatly.
"One of them has to be the openside and that will be Sam and Rico [McCaw] is going to have to adjust his game and become the six," says All Blacks head coach Steve Hansen.

"We want to start the game like that because we think Scotland are going to try to play an open game and we want to put as much pressure on them at the breakdown as we can.
"Those two guys are both good at getting over the ball. But how long Rich plays depends on how well the game goes I suppose.
"He's played a lot of minutes and we have got Liam [Messam] in the back-up so I would suggest if we make a sub in the loose forwards it will probably be Rich that gets subbed off."
There is a nod to the World Cup about this selection, too. What Hansen is particularly keen to avoid is having to test theories, however sound, at the competition itself.
That mistake has been made before. Several times. He doesn't want gut feel to be his only indicator as to whether a specific combination could work. It would be unforgivably bad selecting and coaching to have four years to learn and then use the tournament itself to experiment.
Several times this year Cane has come off the bench and played in tandem with McCaw. It's a combination that has worked well in the latter half of games in 2014.
Cane has got to areas of the field few flankers could and that has allowed McCaw to be both selective and effective about when he commits himself to turnover opportunities.
So now Hansen is taking the opportunity to find out whether it can work from the start of a test. There is no reason to believe it can't and the exercise is really about gaining more confidence in using Cane off the bench in World Cup games than it is about in seeing whether McCaw can handle playing as a blindside.
Those who have been clamouring for the past few years to shift the skipper from his beloved No 7 jersey will probably still be hopeful that a permanent move is on the cards.
Just as Michael Jones was forced, after successive serious knee injuries, to concede that he'd evolved into a more effective blindside than openside, so too are there endless arguments mounted that McCaw should do the same.

It's simply not going to happen, though. Not in the next 12 months anyway, because whatever the critics might think, McCaw continues to convince as the All Blacks' best openside.
He continues to do more work than anyone else; to make crucial plays at crucial times and anyone who says he's lost the art of ball snaffling needs to take a look at what he did in London.
He was beyond good at times in the match at Twickenham in his body position, timing and knowledge of the rules.
All of which is why, when asked if he was curious to see how well the combination works on Sunday at Murrayfield, Hansen replied: "I haven't got a great amount of curiosity.
"If you are thinking whether I'm thinking about turning Richie into a six ... no.
"But it is nice to know they can work together and we need to find that out as that might be what we roll with - Sam as a reserve which we have done."
