Nah it would be fitting if it finished:
Djokovic 22
Federer 20
Rafa 17
And after all this time it's revealed that the best of the era was Djokovic all along.
(The reality is that this won't happen.. 7 more Slams for Djokovic and 0 for Rafa? Imagine that!)
The question is not whether Djokovic can do it, physically. By all accounts he probably can. The question is whether he can do it mentally.
Djokovic is motivated directly by the opponents he has on the other side of the net. Give him Rafa, Fed, and Andy, and he see's red. He will beat them to a pulp, or die trying.
Nadal was always Novak's "Northern Star" in terms of motivation. He has now proven that he has his number. No doubt. He has proven he is the BETTER all-round player.
Nadal, the way I see it, is entering the twilight of his career. If he does not win this year's RG, I think it will be downhill after that. If that is the case, what will Djokovic stick around for ? To beat Tsitsipas and Zverev ? Maybe, but I don;t think he really cares about those matchups. To beat Federer's GS tally ? Maybe, but I don;t think he really cares about it deep down. He knows he is the best of his generation, and thats what matters.
He is driven by opponents. Nadal, in his own way, created Djokovic. When Nadal is no longer a force, will Djokovic find the drive to compete ? We shall see.
