I agree. This is an evidence. Like said "World tennis" in 1977. There is several forums here where about this question. A big majority is agree to say Vilas is n°1. But, mysteriously, you can find some people who think that it's Borg. Maybe they don't like Vilas, and they find very poor arguments to say that Borg was the number one.
