my point is to... well, deal with a atatement that is true or false. Maybe I expect too much from the players, that's another subject. My point was that although Nadal was known as the one that remains stable etc., we can take a look at his behavior in this match and a match against Youzhny and verify the statement
I think that George answered your question perfectly but you ignored that bit for some reason, probably because that part of the question doesn't match with your original statement so it's better to ignore it?
There's mental toughness and then there's match-ups. There's a distinction to be made and one you're not making in this thread. I can't say that this victory from Tomas comes as a big surprise just because I have seen their previous matches.
I actually think that Rafa fought hard. It's not like he folded. He kept on trying to find answers and the second set in particular was close. All their matches have been close even though this is a two sets defeat. It was only a matter of a few points here and there. But the fact remains that Berdych has some weapons with which he can hurt Nadal and yes, it's hard to stay on top of the situation from a mental point of view but it's a match-up situation. You can be tough as nails when speaking about mental attitude but that doesn't really help you overcome the weapons the other guy has on court.
If you have to fight against a person, you can "will" yourself to be strong but what if the other guy is in fact really physically stronger? How far can that willpower take you?
