US Open 2008 was a tough 4 setter (and I said it'd be a minimum of 4 sets), and, and you can be as skeptical as you like about Nadal's injury in the AO 2010, but the fact is, it goes down as a loss due to retirement because of injury. Nadal is a champion. He generally takes his beatings like a man. If he can't continue, then he's injured.
So you've got no point. A fully fit Nadal would either beat Muzza in the US Open semi, or take him to 4 or 5 tough sets in a loss.
