He would have a good candidacy and likely does already have the best resume.
I just don’t believe in this silly ‘marginal GOAT’ stuff, it should be basically unanimous. He needs more Slams for it to be unanimous, simple as that. 1) If we are talking about the literal greatest tennis player ever, given that Laver, Rosewall, Pancho, Federer have all achieved massive success after age 35/36, Djokovic should be able to separate himself in his old age no?
2) Would you still be blowing the GOAT horn if he loses 10 straight times in Slams? 4 to Zverev, 3 to Medvedev, 2 to Sinner and 1 to Tsitsipas? Think about how much crap these guys eat on here and how awful they are supposedly. If they keep him from winning one single Slam, what does that say about Djokovic?
I don’t think I could look at him and say yeah this guy is GOAT for sure. His resume would still be the best but I need to have little doubt. This is more about my definition of GOAT than anything against Novak.
