Davis Cup Titles
Guga - 0
Rafter - 0 (Runner-Up in '99)
Australia won the davis cup in '99. Rafter didn't play in the final, but played throughout the year that year. Not sure how these things are interpreted, but in my mind he does have a davis cup title (in pro team sports, you get a ring if you are part of the team, even if you don't play in the championship games)
It's a tough call, but my vote goes to Rafter. He made the semis of 3 of the 4majors, & made the final twice of the most important major(Wimbledon)
Love Guga, but the FO has so many 1 slam wonders from that event, its hard to compare 3 FOs to 2 USOs(which has very few 1 slam wonders) + 2 W finals.
Also Rafter beat both Agassi & Sampras, the 2 best players of the 90s, in majors, which not many can say.
And I don't think the #1 meant as much in their time, guys were switching every other week it seemed. Both Djokovic & Nadal have reached higher point totals as #2 & #3 than Guga ever reached as #1.
Its a shame that both were so hampered by injury(people forget that Rafter was plagued by shoulder issues throughout his career, even when he won his 1st major in '97, he was already talking about issues with his shoulder. He also had to retire during his 1st round match at the '99 USO-after winning the previous 2 years-& he retired after having a great year in '01 because the shoulder made it too hard to continue to play day in, day out, even though he clearly was still one of the best players in the world)
Both had a lot of great tennis left in them.
Their stories(& Joachim Johansson) should help remind some that reaching your potential in pro sport also involves being lucky enough not experience serious injury.
One other stat on these 2:
Masters Series
Guga-5(I think Guga's best match ever was vs Rafter in the final of Cincinnati)
