Depending on what you mean by “overwhelming”, that’s the way it’s been for a long time. The US has been winning more or less every other major tournament recently. Which puts them far ahead of any other single team in terms of results, but 50/50 certainly doesn’t seem overwhelming.
I totally missed the Sweden game (completely forgot to see if they were starting before the opening ceremonies again). But two things to keep in mind:
(1) This snapped a 44-game unbeaten streak, so if they’re tottering or doddering it didn’t manifest itself until literally right now
(2) Sweden is a VERY good team and has frequently just been the team that had the USWNT’s number. Sweden knocked us out of the last olympics (in the quarterfinals?). Sweden beat us in the group stage a couple of world cups ago. Etc.
Certainly the US isn’t miles better than any other team in the world. But it never really was. Watching the last WC, which the US won, we certainly could have lost to either England or (particularly) France.
All of that said… yeah, the team does seem old. But pronouncements of geriatric doom seem premature. None of us are on the team’s training staff. In any case, hard to imagine we won’t beat New Zealand (on Saturday). So the next big test will be vs Australia on Tuesday.
