As of last week, girls now have carte blanche to play on boys' teams if they can make it. Even when a girls' team is available.
No, Gellatly says, if a girl takes a boys' spot on a team, a boy
can't try out for a girls' squad in return.
If he requests the chance and is denied, he'd almost certainly be
wasting his time launching a human rights case of his own.
If talented girls are arguing that to get real competition they have to play with the boys,
what they're really saying is the female game is weak and not worth playing.
