With Nadal's deficiencies, health issues, and inability to defend any title off clay disqualifies him for all time of being even considered to "GOAT-dom!" He works too hard to win any and every match against nobodies and never-weres! He got what he wanted; dominance on clay for a time, won 9 FO's, and rounded out his record with at least 1 or 2 of the other majors! No other #1 was so imbalanced in their record over the years with many glaring absences along the way! Even Borg who is considered a "Tennis Gawd" won equally on grass and clay; and that was without current technology! I would barely put Nadal in my all time top 10; even if separated from the ladies! Laver won 2 cal. yr. GS's and that was with majors not available to him from '63 to late '68 due to pros exempted! I'm told Tilden, Rosewall, and Gonzalez were the best of their eras so I'd put them above Rafa as well! For years before Federer made his mark, we tried to anoint Sampras as the GOAT, but unfortunately he barely had a sniff of a FO in '96! He successfully beat 2 past milti-champs in Courier and Bruguera, but missed out in the semi's, going out to eventual champion Yevgeny Kafelnikov! I already vented about Martina Navratilova deserving to be in the top 3 due to 59 majors in the Open era, winning the "Box SET" and continuing to compete close to 50; taking her last major at '06 USO with one of the Bryan bros! ;-)
