Recently we had the "Agassi: Federer the best of All Time, Now" thread, which made me ask myself the question as a Federer fan: the praise of which past great for Roger would mean the most to me? I have to say it has to be Pete Sampras. And I know it's an odd formulation, since it really should be the players who care who appraises them and how, but I mean it more as a measure of appreciation from someone of the stature to 'be able to pass judgement' i.e. not Andy Murray saying Djokovic is the best tennis player to ever pick up a tennis racquet (hypothetically speaking). Pete Sampras was a giant in terms of doing what one does best and being consistently the best at it. I think Roger Federer transcended that in terms of adapting (and his superior clay court record attests to that) but in terms of pure spectating pleasure they're dead even for me. This is why Pete's appreciation for Roger is the most telling for me. Let me know what you think with regard to your favourite players.
