Nope Fed got every slam for free before the big three was a thing<<<
You are Hillarious and very well brainwashed by the media. Got slams for free, before big 3 there was more good players than 3, Agassi, Roddick, Safin, Hewitt, Blake yes you could say they dominated for shorter amount of time but grandslams would never be free. Lets say there is 0 good players in the world like you say, i know some tennis players would even get stabbed with a knife during match, saying grandslam is free is very funny statement.
Also funny thing Federer will be forgotten soon, i played cs wingman with player who was from djokovic country i asked ohh so you are big djokovic fan, he answered who dafak is djokovic, i continued to ask him about tennis he knew nadal, he knew fed never heard of djokovic though :DDDDD im not making this up its simple fact, im not saying this is very common and happens a lot but im sure it will happen a lot after they end their careers.
