Federer's problem was more to do with his style of play not so much things happening around him. He used to have a serve and volley type game but the courts he was playing on were not suitable. So he was constantly changing his game and strategies - sometimes it worked and others it didn't - that's where the frustration came from. Once he decided to adopt an all court game he took a lot of the pressure off himself and things started to fall into place for him.
It's a Woman's Day / New Idea Fantasy story that he mellowed because of support from family and so on. He changed his game to become less spectacular but more manageable for himself - that's it.
If Federer were to have been coming up in today's social media climate and faced the same level of shit Kyrios or Tomic have received he would have been destroyed by the media - without a doubt.
Tomic should be praised for getting as far as he has - others who faced similar issues with win at all costs type parents didn't make it this far - like Andrea Jaeger. She tanked a Wimbledon final against Navratilova to stick it to her overbearing khunt of a father.
The media were pretty much oblivious to it for years - though they tell the story now like they knew what really happened. In fact she was clearly the best female player in the world, but she constantly tanked matches to avoid becoming the best player in the world. She was forced into playing the game - and wanted out - ultimately her body was pushed too far and her retirement came at 19 years of age.
Could you imagine what she would have faced in today's social media climate ? The fact her father was destroying her would not have been an issue as long as she was winning, but when the winning stopped the trolls would have come out.
Kyrios, I don't know - his talent is so freakish that I don't think he should be compared with anyone - he's a once in a lifetime talent and I hope people give him space so we can see it fully develop - like they did with Federer.
