With the team to play Italy stacked with younger, inexperienced players, All Blacks coach Steve Hansen will hold a higher ratio of hope to expectation at Stadio Olimpico.
In his 12-year association with the All Blacks, he's learned to never underestimate the ability of test rugby to expose a player's mental frailty or lack of self-belief. He's seen a few crack over the years - good players who earned their selection, then couldn't adapt to the test arena.
Plenty can be done to minimise the risk, but there is still an element of the unknown - there is still no certainty that players are ready to cope with being an All Black.
"The biggest thing is the pressure," says Hansen. "It is not like being in a Super Rugby franchise. The demands are greater. The scrutiny is definitely greater and whether you are a staff member or a player, you walk in to it and you can just feel it. It is there and, for some people, it can be overwhelming.
"It challenges you to really understand whether you are good enough to be there. They have got to be confident and time in the environment helps them with their confidence.
