This thread is ridiculous.
You think there is anyone in Fed's quarter who thought, "Awesome! So glad I'll be playing Roger."
There is no one in his quarter that is going to beat him. He'll have to have an bad day to drop 3 out of 5 sets to anyone before the SF.
What Roger does from the SF stage on is debatable...but please, pencil Fed into the SF now. Put Nole in the Final. Also looking forward to a Delpo-Murray QF that should be awesome.
But people do have better days and worse days. Even Roger. And people improve or lose form. If everyone played the exact same level every match we would not need to actually play the tournament.
However, even without playing 100%, a player like Roger can still will. Partly because he so rarely drops far off his 100%.
Playing 100%, and without an amazing lift by an opponent, Roger will will all of the lead up matches. But with high level opponents, capable of great games even if they are not consistent, there is the chance of an upset. And if there is a chance of an upset every round- then the odds add up. Just because he SHOULD win each match, does not guarantee he will win all of them.
People with easier draws have matches they can bring 80% of their game and still win comfortably. They get a rest.
