If you compare 2011 Nadal to 2012 Nadal, well its no contest, 2012 Nadal was FAR better on clay.
So your post has already been disproved. And 2012 Nadal disproved it without even being healthy. Now he's well rested and focusing on clay more than ever in 2013. Heck, he's already training on clay while the others slug it out on slow hardcourt. Like I said, this is only the beginning.
In 2011, compared to 2010 Djokovic, Murray and Federer had way better results on clay while Nadal had worse.
