But surely you would rather have Puerta, Tsonga or Philippoussis (Nadal, Djokovic and Federer's 1st slam opponents) than Federer or Djokovic?
So, what does that prove?
Puerta made life quite difficult for Nadal in the final, there's no reason to believe Murray would have beaten him in that Roland Garros final.
Philipoussis on fast grass isn't an easy opponent either, that serve alone makes him tough to beat.
And Tsonga? Do you happen to remember who Jo beat in the first round of that Australian Open 2008 before facing Djokovic in the final?
And anyway, the problem isn't that he lost to Federer and Djokovic. People wouldn't be slating him so much if he had at least shown some resistance in his finals, the problem is that he couldn't even put up a fight.
