So your opinion is that Nole 2011 <<< Rafa 2010, right?
Not necessarily, my opinion is that Nole 2011 reached his level because of the huge confidence boost of winning the AO, followed by beating Rafa in IW/Miami. Rafa had that confidence boost coming into AO 2011 (going for the Rafa slam, man on a mission), and it would've taken an awful lot to stop him there, and then the injury happened.
Even with the disappointment of losing the 'Rafa slam', Nadal outplayed Novak for a long time in IW (recently saw it again), until he got broken out of nowhere and then he crumbled (lack of confidence). Same goes for Miami basically. All what ifs of course, but I highly doubt Novak would've beaten Rafa in those tournaments, and therefore he wouldn't have become Rafa's tormentor...and so on.
Yeah Nadull was so injured that they had to carry him on stretcher midway through the match... oh wait.
Some players choose to fight on when seriously injured, as long as there is even the slightest chance of winning, instead of retiring with a cough. Hope this helps. EDIT: Thought you were a Djokotard, but see you're just a Nadal hater. So you can ignore the second part
