Obviously this won’t work for all sports, but things like football, track, soccer, it would allow for de-gendered team, even allowing athletes with the skills but not the genetically-endowed physical attributes to have a place to play.
Note: I know very little about sports and being on a sports team, so please point out anything that doesn’t make sense.
The NFL isn’t male only either. Not supporting anything but agreeing that some sports are segregated by performance
Even at lower levels of football women are typically only kickers.
