Having assumption but at least have some facts to back up, and you have nothing. That's just like saying JMac is not ahead of Roddick and would get killed by him at Wimbledon and the USO.
So why do Phelps, Gretzky, Rice or Jordan are considered the greatest player to their respective sport? Because that's the consensus by general public. Federer is widely considered the greatest tennis player, so he deserve the equal respect. Capiche ?
Tier1(goat): Federer; Tier 1.5: Laver, Gonzales, Sampras, Nadal, Borg;
Tier 2: Lendl, Connors, Rosewall, Tilden; Tier 2.5: McEnroe, Agassi
