I guarantee that the girls on this team are not okay with this, but terrified to speak out.
Terrified with good reason. Coaches and AD's are thinking: "If there's talent out there that wins every time, shouldn't I recruit more of them and bench my losers? My job could depend on it..."
Bound to improve the girls' self-esteem, too, with every beating they take from directly competing with XY's.
They don’t mind having a guy who can beat every girl. They’ll complain when the dude is on an opposing team.
