I agree, Roger had injuries and that was part of the reason he got those beatdowns from Djokovic
On the other hand I'm happy and thankful, as Fed's biggest fan on this forum, that he is 6 years older then Djokovic and was the one who played Phillipoussis, Baghdatis, Hewitt and Roddick, while Djokovic bumped into the GOAT himself and Nadal right from the start. I sometimes think about what if it was Novak or Rafa facing Fed's opposition from 2004-2007, might have taken me away the opportunity to proudly call Fed the GOAT now as he has 17 GS, thanks to the great assistance from Phillipoussis, Baghdatis and Roddick
