Everyone intelligent thinks like me, and here is why: if one player is so important, then tennis becomes worthless when that player retires. Fans of Joker think he will win forever, when in fact his career can end at any time. It may be this year, or it may be in 5 years. But if your world revolves around Joker, then you won't watch tennis when he is gone.
Fed fans are already in that boat. Fed is most likely gone now. He was not having much success after a 2nd operation, so the chances of him doing anything in the future besides perhaps eventually playing some exhos for seniors is very slim.
I think Nadal is very close to the end now, so really it's all about Joker now and for as long as he can stay dominant.
One player fans are going to disappear. You won't see much of people like Octobrina because there you have a one player fan. It was all about Rafa.
A lot of people here will disappear when the Big 3 are done.
The rest of us are looking for younger players who are most like the veterans we most enjoyed watching, so those who love tennis and are not totally obsessed with one player are going to be around here for a long time. The one player fans will disappear, but it's not like they ever enjoyed tennis. The were always miserable unless their faves won.
Meanwhile, for me personally Joker's CYGS quest is more interesting than just about anything else right now because I don't see one young player yet who is an obvious future ATG who will attract millions of fans from around the globe. The young guys to me either have severe character defects (Sissy and Zod) or are very likeable young players who just don't have a complete enough game to dominate.
Lightning strikes quickly in tennis. Guys like Borg aren't even seen on the horizon by most people until a year or two before they break through. I don't think anyone saw Mac or Connors breaking through, or Becker, or Edberg, and so on. 20/20 hindsight makes the breakthroughs seem obvious and predictable. But in real time you just don't see it happening.
I agree with you sir,
I only appear as a fanatic when I see these low iq cretins who are here to bite for their hero as if that is their motive in life. This fellow with gamesetnovak id has been replying me as if he thinks some battle is going on

I put that moron on ignore for some days and was not seeing his post, then I unblocked him as I normally don't keep ignore list with profiles, it doesn't seem "neat", however he is again here to vent his frustration, lol.... Anyway, blocked him 20 minutes back, cannot see his comments as they are nonsense anyway.
Addressing your main point
Yes Nothing lasts forever and just being sired to 1 player reduces the value of Tennis on the whole..... you are right!
I am not sired to Federer like that Octobrina was sired to Nadal, I too will change camp when I see a player worthy of that adulation, sadly I don't see anyone in the current gen of upcoming players/the ones who are playing. So no reason to accept a successor until he shows up, let the next champ arrive, we shall have a new hero.
My view on GOAT is simple.
Sampras, Fed and Novak have dominated 3 decades separately and Nadal has dominated Clay on 2 decades alone.
So it is stupid to say 1 is better than another on pure numbers only.
So when players are so diverse I prefer to compare them on their iconic status and declare the obvious choice Fed as the GOAT, thats my opinion, I don't care if Novak fans or Nadal fans don't share that opinion, unless Novak gets a consensus in the media of being greater by the fans on the whole it is impossible to declare him ahead, Fed still remains 1 and there are many who think like me.
Nd sure, when new heroes comes we will follow them too, Tennis doesn't revolve around anyone's records, everyone will perish.
