Re: Why is Graf overlooked?
Not sure who people are putting in these GOAT threads, but seeing as Nav, Serena and Steffi have been mentioned...
Martina: a player who brought a new level of physicality to tennis. Also, she has stayed active in tennis matters since ending her singles career, voicing opinions on today's game, doing lots of media work at majors, all of which keeps her in fan's minds.
Serena: like Martina, a real game-changer in her physicality. Love her or hate her, Serena has real presence on court, and isn't the shy type.
Steffi: to me, far more shy/retiring than Serena or Martina. She was much less demonstrative on-court. If she hadn't married Andre, would we ever see her?
