I'd say that any of the teams between 2nd and 5th can beat any other team in the same group, it's so tight. Beyond that, you have the ABs who you need a fair bit of luck to beat, and you should expect to be able to beat teams 6th & lower.I'd also say that Argentina are unlucky to be so low in the table. Given how they've been playing in this years RC, they certainly are better than 10th in the world...
