You could definitely make the argument that Borg is the real GOAT due to
that unparalleled surface versatility. At the very least he's up there with Djoker and Fraud. My boy
Pistol and Bull trail those 3 in that regard.
Ouch!
TBF he's one of the few tennis greats who came from a relatively humble background, and we know those types tend to fall prey to the good life so he's not alone there. But yeah, the way he kept splurging despite that court case dogging him for years was downright pathetic even by celebrity standards. Dude had more than enough opportunities to get his life back on track!
Why is surface versatility so important at this level ?
I mean I do understand the overall aspect of versatility, even some of the greatest struggled to be versatile. Mcenroe, Boris, Edberg and Sampras could never win FO, vice versa Lendl, Wilander could never win W.
Ok, so what ?
In the end if you can compensate for that on the other surfaces then isnt that a greater thing ? The Bull won 14 French Opens in 17 long years, isn't that a harder feat to achieve than Federer winning 14 titles combined at 2 different slams (W+AO) in 14 years (2003-2018) ... So Federer doing a 8+6 at those 2 slams vs Nadal doing 14 at 1, which is harder ? I would say winning 14 is hardest because so many younger generations came and he held them off ... Thiem, Zverev etc, he held them off and he also held all the people born in the 1980s also off for this long. If Federer's AO+W combo of 14 as great as this one ?
Thats why I feel versatility is overrated at the highest level. Sure Borg won 6+5 at the natural surfaces which are polar opposite of each other, but then the total is still 11 slams, if someone else manages to win lets say 6 AO + 5 USO, that will still be 11 Slams. In the end Total is what matters.
Wawrinka has won 3 slams (1 each at 3 different slams) while Murray has won 3 (only 2 slams covered here), so we hail Stan as more versatile ? It doesn't matter, isn't it ?
Kuerten has 3 FOs itself, I find that more impressive at least he made a bigger mark on 1 surface while the other 2 won in bits and pieces.
Agassi is known as the most versatile man between Borg and Big 3 eras, he has the CGS ... Ohh yeah, but when I look at Agassi what I see is the only ATG who does not have Multiple Slams on at least 1 of the natural surfaces ...

... Ohh yeah... Sampras, Becker, Wilander, Mac etc etc all have at least 2 slams at either Wimbledon or at the French .... Agassi for all his versatility could manage only 1-1 each on Grass and Clay. Ok you might say hey 90s was greatest polarity in surface bounce and speeds between surfaces, it was super hard to shift surfaces etc. ... maybe you are right but end of the say why should we praise Agassi more for his versatility when he managed lesser slams than other ATGs on natural surfaces in total ? This is why I feel versatility is overrated.
If given the choice to be a 1 trick pony who wins 14 frenchs and another guy who won 8 Aus opens and 6 US opens then maybe I would prefer to be a 1 trick pony ? I dont know, at least history remembers me as a God on 1 surface, no ? Specialisation like nobody has done before... lol... Anyway, that having said, as Nadal demonstrated ...someone who is that great to win 14 french opens titles in this era would also happen to land in 1-2 wimbledons along the way because he is a too great a player to not be versatile at some level, so versatility comes automatically when you are so damn great on 1 surface ... maybe Sampras was unlucky for his stamina issues, otherwise he should have won at least 1 french open... not a big deal... versatility is overrated I guess...
