Should the Argies do the unthinkable, then it's fair to say it'll register around 6-7 on the Richter scale and will match the cameo appearance of Halley's Comet -- the certainty of visibility to the naked eye only twice in a human's lifetime.
Look at it whichever you like, it'll be nothing more than a sporting aberration at McLean Park, Napier, in their Rugby Championship clash.
That is not to say the world order of rugby won't benefit immensely from such seismic jolts but a potent dose of realism relegates such thoughts to flights of fancy.
Fundamentally the tourists have peaked early in their two tests against South Africa to understandably earn a modicum of respect from the All Black coaching stable well before Steve Hansen's press statement in announcing the team.
"There is a lot of respect for this Argentinian team. Their last two performances against South Africa have been right up there and shows that they are capable of beating top opposition," he said in naming Hawke's Bay Magpie Israel Dagg as fullback and giving Otago's Ben Smith the licence to spread his wings on the right flank.
"Capable", that's the operative word in that quote.
Sure, to get under the skin of the Springboks requires a certain level of dexterity but, conversely, doesn't that also say something about the preparation of South Africa?
Needless to say, coach Heyneke Meyer and the Boks will be put through the spin-dry cycle themselves against the Wallabies this Saturday in Perth before the All Blacks host them in Wellington the following Saturday.
It would have been unprofessional to treat the Pumas with disdain because, Hansen and Co will be the first to admit, it's not the result that matters but how the New Zealanders will come through in certain facets of play.
Notably it'll be more the hum under the bonnet of the black machine rather than the analyses of muffler emissions.
But the prudent will argue it's equally imperative to check out the exhaust fumes for fuel efficiency.
Sticking with the motor car analogy, Shag and his assistant, Ian Foster, will be itching to see if the carburettor provides ample air and fuel to the juggernaut and the spark plugs, devoid of cracks and sludge, ignite that perceived sense of sputter-free purring.
Dagg is a spark plug who deserves another shot after Ben Smith's adroitness took the litmus test to another level of acidity at fullback and an air of indispensibility.
While Foster had reportedly made it abundantly clear provincialism isn't a factor when it comes to selection, Dagg's recall is academic.
He knows the nuances of what McLean Park offers, even though it is starting to resemble a kitchen-sink sponge where, in the blink of an eye, a slip here or there could turn one into a hero or a villain.
Beauden Barrett's maiden start at first five-eighth also makes perfect sense -- girlfriend's tweet or not and Aaron Cruden's chest injury aside -- in Hansen's philosophy of trial and error in the bigger scheme of things such as the World Cup in Britain next year.
A treacherous surface and an opposition pack whose upper-body strength can create havoc will make it a baptism of fire for "carburettor Barrett" on 21 caps.
But unarguably therein lies the experiment to ensure there's no repeat of the close shave in the stalemate in Sydney against the Aussies in the Bledisloe Cup opener.
Not surprisingly Wellington's Cory Jane makes way after his intermittent contribution to the collective although Hansen begs to differ.
"The selectors felt this was the right time to give Israel an opportunity. We also want to make it clear that his selection is not a reflection on Cory Jane's play, as we have been very happy with his performances."
Colin Slade slides back to the bench and, predictably, Ma'a Nonu returns from his shoulder bruising to No12.
On the bench, prop Joe Moody replaces Charlie Faumuina and lock Jeremy Thrush comes in for Steven Luatua, on form and tactics, respectively.
Hansen explains: "We wanted a specialist lock for this encounter so Jeremy is the obvious choice with Dominic Bird and Patrick Tuipulotu still not ready to play. In the second change, the selectors have been unhappy with Charlie's form."
Discipline? That, too.
