I believe if that drop shot by fed had been 1/2 inch over into the court - he may have won the match - he was dominating Nadal up to the point. But he let the out call scramble his confidence.Regarding Federer's best RG level I have thought the same, that 2011 was his best even though he wasn't great throughout the year 2011, but many Federer fans here do disagree with that. Can't be sure. Has to be either 2011, 2007 or 2006.
