Look at the All Blacks and their history at the World Cup. They've gone into just about every World Cup as the raging favourites and we all know the record. Australia doesn't have a team that should even be able to get within a whisker of the current All Black team but they rolled them in Sydney. Same situation at the last World Cup.
Realistically, over the past 20 years, for how years could it be said that Australia actually had a better team? 2 - 4years? Coincides with the best years of the Eales era but that would be about it. All of that said, Australia is still the best performing team at the World Cup over that period. I think it would be fair to say we have achieved considerably more with less talent.
The All Blacks will go into the World Cup as very warm favourites again - let's see what happens!
