Except that Borg did it twice.
Also Borg beat Vilas who was another clay court legend. So, Nadal was great this year at Wimbledon, but maybe lacks and inch on Borg. If he wins next year, he surpasses Borg.
And, of course, Borg and the other players of his time weren't focused on records as are today's players -- well, maybe Vilas was.
Agree with this and it was a totally different time. Let's also remember that at the time, Borg just happened to be pulling off 5 straight Wimbledons. I would have liked to have seen Borg play with the racquet that Nadal uses, and Nadal with a wooden racquet and see how they look then.
Mac asked Borg how he would play Nadal, he replied, I would just be much more patient than most of the guys today are, the first set would probably last two hours. (paraphrase)
For those of you youngsters that didn't see Borg play, their ground strokes were similar (power difference due to equipment), biggest difference was IMO Borg had a much better serve. Won a lot more free points on server, hence, the success at Wimbledon too.
