Now as I said if Rafa goes on to end with a few more majors than either of his main rivals, it won't be as significant. However, if he doesn't then the lack of a single WTF title becomes increasingly more significant in grand scheme of things.
Your paragraph above appears to contract the ones below.
For those who disagree I would point them to discussions/arguments on the former player Board. It is clear from them that many tennis fans who weren't around watching tennis in 70's, 60's or indeed even further back, are not aware of all the circumstances that existed at those times.
Most people who weren't around are basing their arguments on the cold hard stats/facts they can see in record books, and not taking into account the relevance of other factors that may have existed.
The same will happen in 60 odd years from now, when the current generation of fans are no longer around. Then as always people will look at the record books and cold hard stats that are listed.
The Greatest Players are the ones who dominate.
If we just stick with the Men's Singles category ...
Sears, Larned, Renshaw, Tilden, Cochet, LaCoste, Crawford, Perry, Budge, Riggs, Kramer, Rosewall, Laver, Emerson all were clearly dominant in the sport during their peak years.
Remember, you can only play (and beat) who you play, regardless of every other factor.
You quickly forget, Roger has 8 Wimbledons, Rafa has 13 RGs and Novak has 8 AOs. It is these wonderful achievements the Big 3 will be remembered for as far as tennis is concerned.
No one cares about the WTF count because the WTF Tournament has always had a level of "Artificiality". In recent times it has only been "Best of 3". In a sport where the greatest contests are "Best of 5", the Majors are the True Test of Greatness. Every tennis player will tell you that, including the Big 3 of today and the Greats of the Past.
In 100 years time, the Big 3 will be fondly remembered as a Group. Which one of the three is viewed as the Greatest of the Big 3 will be debated forever. Most will have their personal favourite regardless of the Statistics because the knowledge of their Careers will be handed down in the form of Word of Mouth, Match videos, and historical Media records.
But unless one of them wins the GRAND SLAM ... the ongoing passage of time will make Laver's two GRAND SLAMS more and more valuable and revered. Laver retired in the mid 1970s - nearly 50 years ago. Yet we continue to mention his name in the same sentences as Borg and the Big 3. Laver didn't win a YEC. Borg won one WCT YEC and two ATP YEC. That should tell you a lot, in itself.
