No doubt. I've seen clips enough of Rosewall and Laver to know that they're quick, Ferrer is another who is very quick despite his height. But Federer, Nadal, Djokovic and Murray are all 6'1 to 6'3 or so and are great movers which good footwork. Against these guys I think Laver and Rosewall would find it very difficult to keep up with. But you're right there is a trade off.
