I think we would have gotten petulance and excuses if they had lost to Brazil b/c they perceived that they were being cheated in that game. But in the final vs Japan, that wasn't the case.
The comments from the man in the street online are terrible though, most show a general lack of knowledge of the game, but also you get a huge sense of disappointment from folks who figured it was an automatic win.
Also a lot of people wondering why the men's games aren't this open. The ppl on tv could do a better job explaining some of the reasons: Size difference in women's teams, better (and bigger goalies), better, more experienced defenses.
My takeaway from this tournament is that with the exception of Brazil, who look like they met each other in the dressing room before games, there was more team play and less reliance on individuals than in the past, and that Japan's and the USA's defenses were superb. Japan had to deal with the size difference against teams that thrive on an aerial attack.
