I honestly don't see why he's getting slated. Him and Djokovic were equal until Djokovic decided he wanted the glory for himself (2011).
As someone said before, Djoko already had a slam and a WTF.
But surely you would rather have Puerta, Tsonga or Philippoussis (Nadal, Djokovic and Federer's 1st slam opponents) than Federer or Djokovic?
Before Tsonga, Djoko faced Federer in the USO 2007 final, he lost but he played a great match, having set points in the first two sets (better than any of Murray's finals).
Not to mention he beat Federer in the Semis to win AO 2008.
