you mean versatile players like chang?
I do agree that the style of grinding has changed though. back then you could grind by just running fast (running speed is highest when you are very young). now we see a generation of "power grinders". they bring everything back but at the same time hit every ball as hard as they can. just running won't get you anywhere you need the power too.
so to hit every ball with full power for 4 hours you might need another kind of endurance and power as runners like chang had.
still theoretically I thinkk the slower surfaces should benefit the younger guys. almost all teenage winners won on slow surfaces first. running speed and endurance are typically young players skills.
