Tilden had Bill Johnston and the French Musketeers for competition. But for Tilden, Johnston himself would have had the same kind of dominance that Tilden had (or not too far from it), and the Musketeers won multiple majors between them. Gonzales was stuck in that 7 year contract he had signed with Kramer. Kramer would always sign challengers to Gonzales like Trabert, Rosewall and Hoad on much bigger money, which only increased Gonzales' bitterness at being underpaid. It's rather ironic that Gonzales was blamed at the 1963 US Pro for negotiating an appearance fee while nobody else got paid because of promoter incompetence.
