Yes Nadal will be a footnote in the anals of tennis history.
I think he will fade in due time. He'll easily be remembered as the King of Clay for probably until human extinction but there's no way he'll be ranked ahead of Roger or Djokovic 20 years from now. And I think Sampras & Borg will gain back their traction because they will have a more easily defined dominant period.
IMO though:
If Novak gets: 5 more majors, 2 more WTFs, 50 more weeks at number one, 1/2 more year-end number ones, and 1/2 more multi-slam seasons than he's easily the GOAT. Another Nole Slam and he'd only have to get to 20 to be the GOAT
If Nadal gets: 3 more majors, 1/2 more year-end number ones, 1/2 more multi-slam seasons, double career slam, 230-250 weeks at number one. It comes down to distribution for Rafa since that's his one "weak link" in the debate compared to Fed and Djoker. If he can get to 21 by having a distribution like 2-13-3-3 then that'd look a lot better than say 1-14-2-3
No, there's no way Nadal is overcoming his lopsided spread. Novak just won his 5th Wimbledon. Nadal is unlikely to get 2 more USOs by comparison, unlikely to get another Wimbledon and a 2nd AO wouldn't overshadow 0 WTFs which it seems clear he's not even trying to get anymore.
I think Novak could just win the next 3 (I know, not JUST but you get the point) and retire GOAT. Because he'd get next year's YE and have 7 in that department, double career Slam, maybe tied most WTFs, will have most weeks and 1 Slam shy of Roger.
