Multiple Major Winner
Hard to explain to people today, but Borg winning 5 Wimbledons in a row on a fast, slick bad uneven grass surface AND winning 6 French on slow as molasses red dirt clay, its hard to quantify how impressive that is.Good stuff, @Moxie and @Kieran - not much to add at this point, except to say that I'm not surprised that you appreciate fountain pens!
Quick question, though, about Borg: Did he actually care about Laver's 11 Slams (not to mention his other records, pro slam dominance, etc)? Presumably he didn't, because if he did he would have gone after Emerson's dubious "record."
Comment about Emerson: Among serious tennis fans, he's sometimes made fun of, or at least derided of due to his--as I said--dubious Slam record (winning 12 when the two best players, and most of the best, were playing pro). But...he was still a very good player. If you look at his Slams, most of them involved good opponents - they weren't like Kriek's two AOs. Now Emerson isn't a real "12-Slam winner" like we think of Borg and Sampras, and he was a lesser player than a lot of the guys who won 6-8 Slams. But he was still a great--or borderline great--player.
Jeff Salzmann, who has "secret Elo data" from before the Open Era that he hasn't shared yet, ranks him #55 all-time (including women), so maybe #25-30ish among men. Just ahead of Pancho Segura, Ilie Nastase, and Frank Sedgman, but behind John Newcombe, Arthur Ashe, Guillermo Vilas, and Edberg. I don't have enough info to really comment on that, but it kind of makes sense to me.
Speaking of Vilas, he's another guy who was sneakily good, looking beyond Slam count. He was a bit like the Andy Murray of the 70s - a lesser great playing alongside some of the best of all time. The Andy comp only goes so far, because Vilas was particularly great on clay--his peak Elo on clay being 5th all-time, behind only Rafa, Borg, Novak, and Lendl. He was pretty good on carpet and grass, but not as good on hards. Meaning, his main obstacle was Borg, who he lost to in two Roland Garros finals (though he also lost some big ones to Connors). And he also lost that 1982 RG final to 17-year old Wilander, but he was past his peak by then. He'd have 5-6 Slams in a Bjornless world.
From winning DC matches at age 15/16 to being like a rock star icon with his public image, there hasn't been anyone comparable to him in mens tennis.
