I'll have to debunk that claim that Vilas is better than Nadal, nonsense
First, there is no specialists in our era because of surfaces having been kinda "uniformed" for the public to enjoy more rallies. Both era were different. Specialists today doesn't mean nothing really or simply an inclination or a preference to a surface. Who would you put as "grass specialist" when talking about the top ? Mahut ? To me, specialization is impossible and only all-rounders prevail. As a matter of fact, the top 5 is only guys that can reach finals on every surfaces. You talk about Ferru but he has as much semis in the French than he has in the USO or in the AO. And his greatest victory is on indoor at Paris !
Second, the competition Nadal had was better and I just need one name : Federer aka The GOAT. Had Nadal not existed Federer would have had 5 or more French Open but Nadal put the beats on him 4 times in the final and prevent him that luxury. You already know where I'm going with this because the second best clay player in that era simply is Federer. And the third best was Djokovic whose game was always difficult for Nadal (remember the epic matches in Hamburg '08 or Madrid '09 ?). In 07 and 08, he lost to Nadal in the semis of the French, in 09 he was also losing to Nadal in semis or finals of Masters1000 tourneys on clay. In 12 and 14 he again lost to Nadal in the final of the French. Djokovic has countless finals on the Major clay tourneys and even more semis that make him unarguably the 3rd best on that surfaces since he came up.
So yeah, 7 years ago, Djokovic was ranked #3 already (we often forget) and was already problem on clay and he still is. When it's all said and done, Federer will be ranked at #1 and Djokovic will be top 5 (if he keeps up with his current form obviously, we can never know but I believe he could easily reach the 14 mark in GS titles and get a French ; and if he does, he will secure that spot and Laver should have to go). So Nadal competition is better than Vilas : Federer > Borg, Djokovic will > Connors, Gerulatis, Nastase or whoever else.
So to end it all :
- Nadal has a career grand slam + numerous Davis Cups + an Olympics title + two finals in the YEC. Reached the finals of every grand slam at least thrice which proves him to be a far better player than Vilas ever was. That doesn't mean Vilas was a one trick pony. But if we hold against Nadal his over-representation of clay tourney in his resume, what is to be said of Vilas or Muster ? The former won 50 of his 62 titles and the latter won 40 oh his 44 titles on clay ! Nadal's ratio is lower (or less high lol) than both.
- And let's be real for a second, Vilas has more titles and more Ws on clay because he was a stat padder. His 1977 season where he won 16 tourneys was full of shytty ones and that's even the main reason he didn't finish at the #1 spot. I mean the very fact he won twice more tournaments than Connors and didn't even end up #1 is proof enough that all the ones he won were worth shyt. And also he only won that French Open because Borg didn't have the right to participate. We both know how it would have ended up if he did
Your turn, gentleman
