I can't comment too much on the game itself as I couldn't watch it in real time (saw the first few and the last five minutes, that's all), but I have a basic grasp of how the teams played and such from this thread. So, neither team brought their A game, as I understand it. That happens. Australia has been under some stress from within the team, and Argentina, I'm sure, could be struggling with the 'trying TOO hard' syndrome that sometimes happens to a team when the pressure is on to get a first win. Both scenarios could account for mistakes and poor teamwork.
Still, I'm guessing if a poor Argentine side went up against a poor Australian side LAST year the Wallabies would still have come out on top. From the previous games I've watched Argentina is an improved side over last year. Yes, they do still make mistakes, but at least there wasn't another 54-17 or 73-13 blowout as in previous years. Do they have areas to work on? Yes. And hopefully they will. Do they have a chance of winning against NZ or SA next year? Certainly, especially if they keep improving and work hard to correct their common mistakes.
The sad thing in all of this is that too many people are taking away from the Pumas victory by blaming Australia, or by saying that it wasn't a high quality game due to sloppy play. Who cares? I mean...really, who cares? No team is perfect*, and teams will have off days and off games, but whether they can hold it together long enough to get the win or not takes a lot of skill and effort, too. And Argentina has hung in there in the RC, not giving up despite a lot of fans who seemingly think they don't belong there. Well, it looks like they do. So let's let Argentina bask in their hard-fought victory, they deserve it.
