I am interested to see what happens with the u17s. The u16s played subpar opponents - that was a club-payoff window dressing show with little scouting due to Covid. Don't pay any attention, just like don't pay attention to CONCACAF blowouts. They are meaningless (except the games v. Canada

)
Typically, US early-maturing players can still overpower most of the smaller and slower international girls at 15/16 years old (there are exceptions like Nigeria). Then they catch up by 18/19. US U20 record is pathetic historically because of that. Plenty of 18/19 year old girls in this country to choose from for that team - shouldn't be any 16 or 17 year olds on it. But Nike has a say, of course, unfortunately.
Bottom line, Japanese and Dutch girls (and Spain) at the same age are more technical players than ours. That has nothing to do with playing together longer, etc. And, I think we are starting to see this same fact start to play out on the full national team with the new players being brought in - fast, strong, but not technical.
Also, note, to those complaining about the defense...yes, Japan and Netherlands scored 3 goals each. But, US offense only scored once in those two games, and that goal was a bit fortuitous.
