You guys act like you know everything and the rest of the world know nothing just because you disagree. Steve Flink doesn't even include Pancho on his list:
I'm sure you all will say he doesn't know anything about tennis history while Bobby say Rosewall, Dan say Hoad, Borg Number say Borg, hoodlum say Laver...are all experts in here and no one knows better. Too funny.
Tier1(goat): Federer; Tier 1.5: Laver, Gonzales, Sampras, Nadal, Borg;
Tier 2: Lendl, Connors, Rosewall, Tilden; Tier 2.5: McEnroe, Agassi
