Yes in part.. but im not sure its the most importnat factor. Can you prove your point maybe..
Who in the juniors nowadays plays like Fed then in your findings ..?
Hold on: you want me to "prove my point"???
Use your eyes: at the moment, how many of the young players look more like Djokovic, how many look like Federer?
In 2011 it looked like Novak had rewritten the rules about how to win. Just be fast, limber, don't miss. Make sure you can hit one more ball than all your opponents.
From that year until this year Federer started looking like a player from the past. He was still beautiful to watch, but he didn't win.
His 2012 Wimbeldon almost looked like a nostalgic trip down memory lane. His last major final was more than a year before. He didn't make another final until two years later.
Surely you know how it was in this forum for those years, with people predicting about 30 majors for Novak.
Ask yourself who most of the younger players look more like, Federer or Djokovic? Think of A. Zverev, Coric, others. Dimi is the only guy I can think of who resembled Federer. Thiem to me looks like a blend of Nadal and something else, and he even stands way back like Nadal (and loses on fast surfaces as a result.)
Going back to Evert's era, Austin was a direct result of Chris, similar style, and you can bet that most people were copying Chris, not Martina.
Because who was Martina up to around 1981? Answer: the person who used to lose to Evert most of the time.
Up to that same year it was Borg who was setting the world on fire, not McEnroe.
No one was looking to a young player to dethrone Connors, Evert and Borg while these guys were dominating. It was all about two-handed backhands and baseline play. Wilander modeled his game to a large extent after Borg, and even Lendl, with a 1HBH, was more a baseliner. JMac was an outsider in terms of guys winning majors until Becker and Edberg reset things, followed by Sampras.
What changed this year? Old Man Fed has won two majors, and now, suddenly, the whole world is saying: "Maybe his way IS better, if he can still win majors at the age of nearly 36."
So don't be surprised if you see more young players now copying the styles of people like Fed, Sampras and so on, as much as possible. But we won't see that for a few more years, because all the very young, top guys grew up seeing Novak have more success.
(Kyrigos is an outsider, but can he win big matches?)
