At a certain point, players get "old", sports-wise. This was that tournament for many US team leaders, like Rapinoe, in particular. Then, they had injuries to their midfield and their central defense.
And the coach didn't really play any of the bench, when we were getting over-run by other teams in midfield. It's like we imported a coach with 1990s era tactics to boot it long, and just let the physically-superior US women run down the ball, power past the defense, and muscle it into the net.
The US needs to adopt more modern tactics. But to do that, the US has to develop players with better technical skills. We don't have to go gegen pressing, but if we played to our strengths as a nation, that's what we'd do, until we can start developing, recruiting or identifying players with better on-ball technique.
We have some very talented young players, but they don't really have a coherent team concept. It was just awful to watch. The one US play was to boot it long toward Alex Morgan (very cute, by the way ...), who basically just tipped a header forward for someone to run onto.
That was the whole freaking offense! Has this manager ever watched the men's game in Europe, like anytime in the last 10 years ???
