Maybe. When I watch I reach a different conclusion.
I was looking at the 1969 finals Laver played and was not impressed at all. And that was supposed to be his best year. Compared to how tennis is played today they looked, to me, significantly less athletic and moved much less.
I've seen Rosewall and Laver play live, up close. I've also seen Federer, Djokovic and Murray live, and virtually every all time great player in between them. Today's players have nothing on Rosewall and Laver in terms of talent and athleticism.
