With two games behind them, I'm fully expecting Argentina to be competitive and challenging opposition for the All Blacks.
The Pumas' first game in the Rugby Championship was misleading. Most of their squad play in France, which is both a different level and style of rugby.
So when they came together as a team to play the Springboks in South Africa, I think it was a rude reality check: the Pumas are physically good enough, but the top two inches were probably not fully engaged. That result woke them up and when they headed back to Mendoza, I thought their tackling and ball carrying was great - really physical and robust.
I fully expect the All Blacks to win in Hamilton and it's obvious that they feel they need to improve some aspects of their game that weren't quite right against the Wallabies. But the key difference between the Wallabies and Pumas is that the latter have a steeliness and hardness to rely on in the final half hour. That difference will be noticeable in the scrums.
The Wallabies have always struggled with the hit. Under the new laws, that has not been such an issue but they did struggle with the push. They have so little teeth - they just don't seem to have the power - that they were getting done by the All Blacks.
