Stan and Murray are inferior specimens who would not win a lot of slams in other eras, these sorta jokers are not ATGs,
Stan is that loser who has been Fedal's pigeon for more than a decade, Murray is another loser who has never beaten peak Fedal in slams
Meddy/Tsitsi/Zverev would never reach the semi finals in other eras too, these are not champions at any level
Actual ATGs below Novak would have made him retire by 2020 and Fedal themselves would be retired by 2018.
Fedal would have stopped winning slams by 2014-2015 and Novak would have by 2018 if real ATGs had arrived in Thiem/Grigor's gen
Guess with, that kind of ATGs don't grow on trees. You're talking about ATGs level Samprass, Lendl, Djokovic, Federer, Nadal. Even though Big 3 are Gods, they are on level no one will probably achieve anymore.
Stan is a late bloomer, and if it wasn't for injuries he would have win more, at least more Masters.
Sir Andy Murray is easily an all time great tennis player, 3 GS, 14 Masters and 2 Olympic golds, who would have win more in not for his hip injury in 2017.
Medvedev, Tsitsipas and Zverev will be multiple slam winners, and I'll keep repeating that untill they do that, in 2 years max. They are changing the game bearing in mind their height and movement.
Fedalovic will keep winning Slams untill they retire, no matter the competiton. No matter what "era" it is. Especially Djokovic who has proved that in 2021, he's hungry as ever. Honor them.
