These guys are so good that the moment you slip even a little bit, you start to lose badly.
I will say this for Nadal, I can't ever remember him going through a stretch like Djokovic did in the final. Pretty much all players go through stretches in matches where they make multiple mistakes and get sloppy for a bit. Even Fed did from time to time. Nadal never seems to beat himself. It's just almost impossible to beat that guy 3 sets. I watch him sometimes and wonder how he ever loses.
