Is this a thing that actually exists? The only comparable examples I know of are of no help to women at all. They tend to be split between amateur and pro - but they would still be dominated by cis-males. Obviously there are leagues in which teams can get promoted or relegated but again, in say the FA in the UK all the teams are male and probably will remain that way. I can see women getting into sports where there are specializations - coxes in rowing etc... baseball relief pitchers who have some special throw, etc... darts, snooker (oddly enough men seem to dominate these sports too!) Also I know of things like rugby sevens where the best teams play for the cup, the less good ones play for the plate and the worst ones play for spoon - or try to avoid it. Still, even the worst teams would probably be all-male affairs. I know of veterans leagues which use only over-40s but again all male.
I literally can’t see a way of women being competitive without their own leagues. So yeah, I agree with luchog about being clueless regarding luchog’s fix, despite luchog not giving a rat’s arse about sport. I await enlightenment.
