I'm more impressed by Federer being able to hit on-the-rise than McEnroe, especially on the forehand side.
McEnroe, Seles, and Agassi could do it easily, mostly because of their stroke mechanics. I should also mention Date-Krumm, because her strokes were the opposite of "natural", yet they are highly effective.
I'm not so sure about that. It takes incredible timing and great hands to play like McEnroe. If it were so easy, everyone would have been doing it back then but McEnroe was the only one I can think of who could hit groundstrokes with a limp wrist and almost no takeback and be very effective. Today, it seems everyone can hit with modern strokes.
