Darth has actually said that Rafa played better than Novak. The roof helped Novak. If that weren't true, he'd have asked for it to be opened on Day 2. But I really do think that Rafa missed chances he wouldn't normally miss. Novak basically stole the 3rd set from him. He never should have let that happen. That was mental, IMO. And after winning the 4th in such a fashion, he should have run away with the 5th, and didn't.
I would say that the 1st and 3rd set were more mental than the 5th set, Moxie. In the 1st set, Nadal was just scared to hit the ball hard against Djokovic which annoyed at the heck out of me, then we all know what happened in the 3rd set tiebreaker.
As for the 5th set, both players went to toe to toe with each other. The key difference is that Nadal did not made THAT return against Djokovic serve (especially that 4-4 30-40...). And I knew that if Nadal could not return that serve, he will lose the match because Nadal will get nervous and dump serve.
The thing about Nadal especially at age 32 is that he will more than likely blink meaning lose his own serve even after getting the break. I think as he's gotten older, he became more susceptible to the "yips." It was unfortunate but all we can do at this point is to move on.
However, I do think that kind of performance will give Nadal some type of confidence to win another slam outside of Clay, I promise you that!
