Nadal fans tend to rate 2008 as his highest level as well.
But sure, it's just Fed fans.
Saying 2011 Nadal is the best at the FO is almost as bad as when you compared Federer's movement to Isner's.
Nadal had his best clay results early in his career, it's good for them to rate his 2005-08 opposition highly.
