They are the ultimate grinding team and no other side in world rugby knows better than them how to stick to a gameplan.
When it comes to all the important matters that are necessary for teams to do well in tests, Argentina are ahead of Australia. The Pumas will fancy they can beat the Wallabies in the last game of the championship in Rosario. Given that the Wallaby forwards would be nervous about scrummaging against a wet blanket, the Pumas have every reason to target that game. Australia have rugby gold in their backs: and tin in their forwards.
Watch the Pumas stare them down then beat them up - and grind their way to what might be their only win.
A solitary win and some competitive work in the other five games would be a fair return in their rookie season. But it might be more. That depends on how much influence Sir Graham Henry is able to wield in his consultancy capacity.
The Pumas can win the ball and keep the ball - Henry has been helping coach Santiago Phelan understand the importance of using the ball. The Pumas can compete if they can replicate the same intensity they offered at the World Cup - but to regularly beat the Wallabies, Springboks and All Blacks they need to be able to score more tries: develop better starter moves and take more risks.
If they can add that part to their offering it might be more than just the Wallabies who are embarrassed this year.
