AB's vs Arg

I think the AB's will win this game, but I also think there are one or two realists out there that might point to this game as a potential banana peel for them. The Pumas are playing very well at the moment, and they have just beaten us and the Aussies, and their game against the AB's two weekends ago was a lot closer than the scoreline suggested. I wonder if the Pumas won't be backing themselves to cause an upset against an AB side that has just been proven to be beatable? Imagine for a moment if they did do the unthinkable and beat the AB's? If that were to happen, and we managed to beat the Aussies, there would suddenly be three teams in with a shout of winning the Rugby Champs in the final weekend. Wouldn't that be awesome?
