Re: Name players destined for greatness if they got in better shape.
Well Lindsay Davenport, Mary Pierce and Martina Hingis prove that, however much working out a player undertakes, there is always a limit to how much they can improve. To be an athlete, you have to be a born athlete.
Monica Seles and Jennifer Capriati often looked like they needed to lose 14lbs or more. They were both great players, so one wonders what they could have achieved with some discipline. Maybe they wouldn't have incurred so many injuries.
Others that spring to mind: Tanasugarn, Casanova, Serena Williams, Rezai.
To be honest, there aren't many corpulent players on the women's tour now. It makes us realise how athletic the sport has become.
Controversially, because they are rarely acknowledged as being over weight, I think these players could lose maybe 7lbs for their own benefit:
Venus Williams (she's not as svelte as she once was)
