Ridiculous stats. So Federerīs US Open 2006 draw was harder than Nadalīs US Open 2010 draw.
Q 2006: Federer against world no.7 James Blake
Q 2010: Nadal against giant killer Fernando Verdasco
S 2006: Federer against world no.6 Davydenko
S 2010: Nadal against Youzhny (who won in five sets against Wawrinka in the prevoius round)
F 2006: Federer against Roddick (he used to be a slam contender)
F 2010: Nadal against Djokovic (who won in 7-5 in the 5th set two days before)
Maybe it shows only that the rest of the field gets worse so that a player like Murray can reach all slam semis in a year ...
Also, he didn't play a single top 5 seed in two of his slam titles: the 2007 Australian Open [10th slam] & Wimbledon 2009 [15th slam])[/i]
So, according to you it would have been a greater achievement if he had beaten Nadal at the Australian Open 2007 although Gonzalez was way better in that tournament. Or it would have been greater if he had beaten Murray in the Wimbledon final and Djokovic in the semi, although both of them lost a better player in the previous round.
