Re: Best passing shots?
Most of the non-Nadal votes are from biased fan bases.
The current greatness league of active players in order of achievements to date (a factual comparison rather than fan biased assessment):
Federer 17 GS, 6 Year End Masters, 21 Master Series.
Nadal 11 GS, 0 Year End Masters, 24 Master Series, 1 Olympic Gold.
Djokovic 6 GS, 2 Year End Masters, 14 Master Series.
