The only teams putting consistent performances together are France and Ireland. Everyone else is up and down for a variety of reasons but it's fair to say that international rugby is far more competitive than it's ever been.
The All Blacks won a lot of games in the 2000s by being fitter than their opponents. That's long gone, everyone is very well conditioned.
I do think teams are generally a year behind where they normally would be in the WC cycle, but I agree, I can't recall a time where anyone in the top 8 could beat another in the top 8 on a day.
