He even said on another occasion that the only thing Sampras had that was better was his second serve.
This is a very silly statement refuted by every statistic known to man but It made me wonder...
Is there ANY big server Federer had a better serve than? Well, Marat Safin has similiar stats to Fed in aces and first serves won (actually slightly worse in first serves won, even).. So that would be it..
Federer IMO better than anyone else besides the big servers. Now that's a great serve but not in Sampras category.
