The majority of women playing in the AFLW wouldn't get a game of A-grade ammos. The differences are that big.
Even in cricket, a sport that is far less reliant on physical strength and which has had a worldwide women's competition for decades, very few women who play for their country are good enough to compete in men's grade cricket, let alone against male professionals in first class/List A.
My point is I've seen male senior players that would be lucky to get a kick in a decent u/16 boys side. We can't assume every trans woman that's playing football was any good to start with.
