Kournikova: obviously not. She couldn't win a tier two title. And she played some of her best tennis in 1998 when the field was probably at one of its all-time weakest points. I suppose she could have if she'd been given Myskina's draw at the FO 2004, but so could have most top 10 players.
Impossible to tell with Golovin because her career ended so early, like Vaidisova. Might have won a slam (Schiavone did), might never have made another semi-final.
