I'm not sure if Tilden's personal rankings of ATG's have been listed yet. They are not easy to summarize, because they changed so much over the years. In January 1934, just before starting his first pro tour with Vines, Tilden gave these as his Top 10 of all time, ranked in order: 1. Henri Cochet 2. Norman Brookes 3. Rene Lacoste 4. Hans Nusslein 5. Bill Johnston 6. Vincent Richards 7. R. N. Williams 8. Jean Borotra 9. Bruce Barnes 10. Karel Kozeluh Tilden had played Vines a few times as amateurs but he was still holding off on giving a full opinion. He had not been terribly impressed with Vines yet; I believe he had even picked Bunny Austin to beat Vines in the '32 Wimbledon final. But soon enough Tilden changed his mind. In January '35 he placed Vines at the top of his list: Detroit, Jan. 22 (AP)—Big Bill Tilden, 42 years “young” and still knowing a trick or two about tennis, today described Ellsworth Vines as the “greatest player in the world today and probably the greatest player the game has ever seen.” “There isn’t a player in the game today that can touch Vines and without a doubt he’s the greatest player in the world today. It’s impossible to really compare a player of today with one of yesterday, because the game progresses and the greatest player of today should be the greatest the game ever has seen. “I dislike trying to compare Vines with Cochet or stating that Lenglen was better than Wills—and I think she was—but I do think that in all probability there never was a player better than Elly.” After Vines, Tilden listed the following players as the best he has ever met: Henri Cochet, Bill Johnston, Hans Nusslein, Karl Kozeluh, Norman Brookes, Gottfried von Cramm, R. Norris Williams, Jean Borotra and Rene La Coste. He made it plain that he was not listing them in the order of their ability. Tilden had a very poor opinion of Fred Perry -- whom he had never played as amateurs -- due to Fred's unconventional strokes. When Perry signed a pro contract in late '36, Tilden predicted that both Vines and Nusslein would destroy Perry and that Fred "will only be amongst the first five or six players in professional tennis circles." But again Tilden was willing to change his mind on hard evidence. In early '37 he played 7 matches against Perry, winning 3. Meanwhile Perry nearly won the world championship series with Vines (32-29), and Tilden admitted in one of his newspaper articles that Perry was doing much better than he had thought possible. In June '38 Tilden published a new book, Aces, Places and Faults, in which he said that finally playing Perry himself in those 7 matches had changed his opinion. He wrote: Nusslein, with Vines and Perry, must rank as one of the three greatest players in the world. In my opinion, all three are slightly above either Budge or von Cramm. Tilden added that over 365 days (what he called the best "average standard"), the greatest were Nusslein, Perry and Lacoste, in that order. He listed these as his Top Ten overall (in alphabetical order): Brookes Cochet von Cramm Johnston Kozeluh Lacoste Nusslein Perry Richards Vines He listed only those whom he had played. Budge was one of the few top names he had never met. So Tilden would not rank him, but he did say this about where Budge's level of play had stood a year earlier, at the time of the Davis Cup classic against von Cramm: I believe at that moment Vines, Perry and Nusslein could all have beaten Budge, but time may soon change that. In May 1939, at Wembley, Tilden faced Budge for the first time, and lost 6-2, 6-2. Irish Times reported: “Do you think that Budge is better than Fred Perry?” Tilden was asked. “I don’t think; I know he is,” he replied. “I played well enough to be satisfied with my own form, but he was just perfect.” On that European tour, Tilden took 2 out of 10 meetings with Budge. Upon return to America, Tilden told the press that Budge was the best player he ever faced. In February 1945: “For 365 days out of the year, Don Budge,” he replied. “He was superior to Ellsworth Vines and demonstrated it. Vines could attain a higher peak, but not often. Sustained quality is greatness. When Vines was bad he was awful. Even when he was off, Budge was great. The test of a champion is the ability to prevail when he is not right.” In 1950, three years before his death, Tilden was overwhelmingly voted as the best player of the first half of the century; and he gave his own rankings. Tilden got 310 votes out of the 391. Rated far back, in order, were Jack Kramer, Don Budge, Mrs. Helen Wills Moody Roark and Suzanne Lenglen. Tilden’s nominees—behind Tilden—included Frenchmen Henri Cochet and Rene Lacoste, Little Bill Johnston, Budge, Fred Perry—he mentioned Francis T. Hunter and Vinnie Richards—and Ellsworth Vines. He flatly refused to pick one over the other; all, he said, were so tightly grouped, separation was impossible. The older stars came first. Then—whether by afterthought or intention, who can say?—came Kramer, Bobby Riggs and then unstinted but delayed praise for Ted Schroeder, Pancho Gonzales and others of the more modern era. I've always found Tilden's writings about other ATG's among the most intelligent and interesting. Like anyone else, he had his biases; he was opinionated, but also flexible, and willing to change his mind upon evidence. He tended to start off skeptical about any new sensation, but over time, and particularly after testing a new player oncourt himself, he could be persuaded to change his mind -- and he was always willing to be completely up front about this.
