The weak era was first used against Federer, then Fed fans started to use this argument against Djokovic or Nadal.No.
RF fans were totally against weak eras a decade ago. They made a 180 since about 5 years ago and try to use the weak era argument to diminish Novak as a player just as they'd worked tirelessly to diminish Rafa. Unfortunately for them, Rafa and Novak diminished RF. Poetic justice.
Weak eras exist. Because if they didn't that would mean that humans are robots. I.e. every generation is factory-produced and hence the same.
Definitely humans are not robots, but if a period was stronger, that doesn't mean we have to put an asterix on other periods that had less competition, much less putting down a player with these arguments.We had this conversation before.
