First ever win is largely attributable to expanded field I would guess.
Conmebol is historically not strong in women's soccer except Brazil.
I guess regarding the hype, I think it was unfounded or based on the last two world cups. I am not sure how I would judge most talented - that is a difficult thing to assess. The fact that the US had no replacement for Becky Sauerbrunn speaks volumes to the lack of depth. For me though, the problem is not the forwards, it's the mids. Sullivan is just not close to peak Ertz level. Damelo is nowhere close to LaVelle. With Ertz in the game, the 8 (Horan) can stay forward and basically add an attacker. With Sullivan, she is having to drop much deeper and put even more pressure on the 10. My point was that the hype was based on past performances and ignorance. I also think some corners of the world love to throw shade on the USWNT so they are just waiting to gloat.
Germany's elimination is shocking. Still, the US now gets their bugaboo team Sweden without LaVelle and then Japan, who has looked like the best team in the tourney so far (though I think their result against Spain is not reflective of how good they are).
As far as development, the US is screwed because our programs are run for egotistical and greedy local clubs. European pro teams are trying to develop pro players so they focus on development. Our clubs focus on volume and unrealistic promises of college scholarships. Until the US finds a way to prioritize development over wins, we will continue to decline.
