I don't want to get involve in this debate, but since both Nole and Gilles are my faves, I just want to point out the difference between the 2 that resulted in a very different outcome of their respective matches after their marathons.
Nole probably spent his off-season training hard and healthy, he has a big team to help him for everything to get his preparation as perfect as he can, he didn't play much in the first 2 rounds, and although the Wawa match is a grueling affair, he recovers well, probably his straight diet helps.
Gilles on the other hand spent his off-season recovering from his injuries, the neck injury that is caused by some abnormality on his spine seems to recurs every other week, and he suffered that shoulder tear during the last summer around USO time. His body is very beaten so his goal in the off-season was to heal all wounds. During Brisbane he admitted that he wasn't very well prepared for the new season bcos of all the healings that he had to do. During Sydney he pulled out bcos of that damn recurring neck problem, in Melbourne he picks up a cold/flu. He had played plenty of long 5 sets matches before and he said he had never cramped like that before on court. During all his first 3 matches he blows his nose in almost every changeover. I suspected that he lost those fluid in his body without realizing it. But anyway, my point is, his extremely bad condition after R3 is really due to a lot of reasons that other ppl don't seem to know or care. And to compare his condition with Nole's is just not logical. Nole is very fit before the 5 setters, maybe he's down 10% after but that means he still has 90% remaining. Gilles on the other hand is hardly 60% before that, and after that he's like 30%. And that Nole's 100% is of course higher than Gilles's 100% to begin with, you got the picture why they were so different after their respective 5 setters.
Well, you should get involved more often then..
That's hard facts and a logical explanation for a very obvious difference in the state of these two.
It takes the Simon comparison argument down, which is pretty much the base of all possible misunderstandings and misjudgements.
There is always a logical reason for everything and when none is brought up it's normal to have speculations from all the spectrum.
thanks for bringing this one up
