You posted an article earlier about the rest of the world catching up to the US. Seems like the rest of the world is catching up in general.
Just using the world rankings, three teams from Post 4 advanced, and none of them were New Zealand’s group. Four teams from Pot 3 advanced, including two that won their group (though Switzerland was in New Zealand’s group).
Of the 6 top seeds that were in Pot 1, only three won their group and one (Germany) didn’t even advance.
Seems like I’ve heard a few “first ever win at the World Cup” also.
