Have to give this to Federer. Just an incredible player who can bring it in any era and a pleasure to watch. I know many will point to his H2H record with Rafa as to why he can't be GOAT, but that's really more a matchup problem than a who's better than who thing. Would have been interesting to have seen what would have happened had Rafa played with his natural right hand instead of being converted to lefty by Uncle Toni.
