Bobby, just as a friendly advice, don`t use your supposed relationship to Bud Collins to strenghten your points. As true as it can be (i don`t find any reasons to doubt what you claim, as i don`t in any other poster), it just makes you look insecure. Besides, this patronizing tone of yours is disrespectful to the other posters. You are a very knowledgeable poster, i give you that, try to convince the others with arguments, which you have by the way, but avoid the arrogance.
Regarding Rosewall`s competition, it is true that he faced valuable opponents in the early 60`s, and in the years outside his prime he proved his talent by beating the best numerous times. The records are there ,not the 23 majors you claim by the way , that is a twisted true and you know it, at best you can say that he has 4 amateur majors, 4 open majors and 15 pro majors, but equating them all would be a mistake. Back to topic, the fact remains, when he was the dominant force on men`s tennis, his 3 main rivals were somewhere absent so to speak. Hoad with many health issues, Laver in the amateurs and then maturing in his first pro year and Gonzo being a part time player. In addition, he didn`t have to face the best amateurs, how do you know if Emerson or Santana wouldn`t have improved in the same way or at least at some exetent, as Laver did?? Competition is what makes a player better, Laver improved immensely just by facing the pros in 63, aided by his supernatural talent of course, Federer went from being a super talented kid with a giant potential to being a GOAT candidate in just 2 years (02-04), he
has stated many times that the 2 aspects that he had to change in his game to become the best were his mentality and his backhand. Hewitt and Nalbandian abused his backhand until 2004, look what happened after his improvements.
Rosewall greatness is not in doubt, at least from myself, he is not a GOAT candidate for me since i only have 2 of those (Fed and Laver), but i can understand if someone make an argument for him.
