1 That the jury is still out on Beauden Barrett as an international starting first five.
While he showed the full repertoire of skills required to fulfil the starting role across the two tests, including answering his coaches' challenge of taking firmer control of the game, Barrett needs to merge those two performances into one and then repeat with regularity to fully convince that he can compete for the top job in the No10 jersey.
2 Argentina's passion is a hindrance to them improving at international level.
You can put their over-the-top reactions to decisions against them or a mistake of their own doing down to Latin temperament as much as you want, but until they can learn to channel that energy intelligently rather than expend it unnecessarily, the Pumas are not going to beat top-ranked teams regularly.
3 Joe Moody is going to be key member of All Blacks pack in the coming years.
Against the much trumpeted scrummaging might of the Pumas, the 26-year-old loosehead's impeccable technique coupled with his physical attributes and obvious strength proves why forward coach Mike Cron took an insightful punt on him, while his work rate around the field was equally industrious. A full season of Super Rugby will be the making of him.
4 Argentine players will benefit from the week-in, week-out grind of Super Rugby.
While the majority of their top players ply their trade in the United Kingdom and Europe, not all of them play large amount of minutes consistently. Super Rugby will help better condition them, physically and skill wise, to play the way coach Daniel Hourcade wants them to for 80 minutes, not in fits and starts.
5 The changes to the scrum engagement are working.
Up until Napier I was starting to doubt that this, but the McLean Park test, more than yesterday's match where the dark art of front row play caused referee Craig Joubert much angst, proved that when two packs want to scrum, it remains an enthralling and pivotal contest in a game of test match rugby.
6 The All Blacks back three of Julian Savea, Ben Smith and Israel Dagg is the world's best and by a lot.
Whether in the wet of Napier or the more user-friendly climate of La Plata, this trio operate at another level in terms of skill, pace, vision, assuredness, decision-making and, particularly in the case of "The Bus", power.
