re: the SET rankings, the link appears defunct. Any such ranking's use is diminished without knowing the formulation for the ranking ...if the user knows it, I'd like to see it-- Billymac00 03:23, 1 June 2006 (UTC)

[edit] Rankings
Using statistics, likely any list of all-time greats would include (not in any ranking):
Men - Sampras,Laver,Emerson,Borg,Lendl,Agassi,Connors,Tilden,JMcEnroe,Perry,Edberg,Newcombe,Becker, and Rosewall.
Women - Graf,Court,Navratilova,Evert,Moody,King,Lenglen,Connelly,SWilliams,Goolagong
One ranking formula weights Grand Slam (GS) final appearances, GS titles, career duration, overall ATP/WTA singles titles, and a factor for how many different Grand Slams were won.
The above has not yet evaluated some older players(pre-WWI). I will provide the raw rating formula: K1*[GS finals+K2*GS singles titles]+ K3*ATP/WTA titles + K4*duration +K5*(GS doubles titles). I used K2=3,K3=0.1,K4=0.2,K5=0.1. K1=1.25 if won (4) different GS, 1.15 for 3, 1.10 for 2, 1.05 for 1 and 1.0 for none. The evaluation is gender-neutral and was derived without bias and apriori knowledge of the results. There would be some band (5%?) where numeric difference between players is insignificant. It allows one to do "what if" scenarios on active players like say Roger Federer.
Any rating system should reward success, breadth of play (considering both surface and singles/doubles formats), and impact/dominance on the game. "Duration" is a measure of career length, perhaps defined as the years between first and last qtr final appearances in a Major.
One can start from basic ratings and use other factors to arrive at their own individual order for all-time greats. Comparisons between players of different eras is not simple or straightforward to do. I would doubt any system that did not result in Graf and Navratilova ranked in the top women.
[edit] Traits
Looking at the list of all-time greats, most will have:
-at least 50 singles titles or Olympic medals
-10 or more Grand_Slam_(tennis)singles finals appearances
-7 or more Grand Slam singles wins
-have a career duration (as defined) of 10 or more years [measured from 1st title to the last appearance in a Final].
-have won at least 3 of the 4 different Grand Slams
-dominated during their era
[edit] Outliers
The male players will usually be tall (Agassi is one exception). It is uncommon to find players performing well on both grass and clay (Borg is one exception).
[edit] Interruptions
Pure statistics cannot account for nuances like career interruptions (Hingis,Capriati) and injury/catastrophe (Seles). Many would not question that Seles would have been on the list without events.
[edit] Active Players
Among active players, Federer, Hingis, Henin, and Davenport have the best statistics to move onto the list (as of 2006).
[edit] Next Tier
Remaining players who would be in the next group of great players might include Hingis,Trabert,Seles,Wilander, Federer, Davenport among others.
