I agree the Pumas were terrific on defense during that 2012 campaign. But something happened, probably fatigue, after their Wales game. They were still good in Paris, but France were on fire that period, but then completely dominated in Dublin. Not to take away from the Irish, but the Pumas just seemed to not have it in them, one game too many after a long year, nothing like the all-conquering squad we'd seen ease through their Cardiff stop. And in 2013, just a disaster of inconsistency, and shipping 70+pts in Johannesburg was just strange.
Hopefully this year is a good one again, but Rugby fans and world community will have to be very vigilant and intelligent with their interpretation of Arg's results: all three of NZ, AUS and SA are red hot, if not on fire atm. Argentina happens to play the 3 ***ans of world Rugby and don't get a game against Italy or Scotland (sorry fans of those !...), it's all 100% Rugby Hell, the highest possible level. Out of the 6 matches they play, at least one big pounding is heftily due.
