Dead/retired players were at least that good at some point in time, female players cant break tru u-15 boys treshhold at any given time, and i say it as a 0 talent for football/soccer guy(altho i had and have tons of love for the sport, trained almost every day up to 8hours in my teenage years, played with and against much more talented guys who could do twice as much with half the effort), u can clearly see those female players spend less time training total as adults compared to teenage boys, thats why their technique/ball controll/shooting/passing/dribble abilities are so terrible, its not just male vs female physique which are colorado canion of a gap apart, its everything else on top of that too
Here recent female wimbledon winner for contrast:
U can see talent/skill/tens of thousands of hours yearly spend on training here, no avg or even above avg male amatour tennis player could even get close to that, she will demolish such a guy w/o needing to run on the cort, with skill/accuracy alone.
