That seems a little unfair. I've seen several other Brazilians and they were definitely fighting for it. It can be a lack of quality, mistakes being made, bad luck, bad shape or a combination of all that, but that's all something different than not fighting for it and I really doubt they were actually thinking "Ah I'll try but never mind"...
Although I do see the same here in the Netherlands, with people saying they barely tried. That's just unfair, even if the performance was far below par, probably nobody is more disappointed than themselves in reality. Because you can bet that they all tried.
