The real unfair disadvantage has really been for players like Hewitt and Roddick, who could play very well on grass, and not on clay.
The fair thing might be to add a grass MS. Players with clay court credentials have THREE T.M.S, and players with grass court prowesses: none.
Take Andy R for instance. He could even be #2 with a couple grass court T.M.S's up for grabs.
I understand your point on one hand.
But on the other, there's just so few players who can play well on grass anymore. It's not just the clay court players - a lot of the hardcourt players can't play it either.
When I first started watching tennis, players could play all surfaces. Yes, they may have excelled on one surface more than others, but they still did decently on the other surfaces.
Now everyone specializes...either on hardcourts or clay. Again, very few on grass. And it's probably because there is only 3-4 weeks on grass each year but months on either hardcourts or clay.
I wish the players would try to up their games on all surfaces. Including grass. But just don't see it happening.
