We get female versions of other main sports shoved down our throats by the media (rightly in general, imo) but nada on American Football. With the amount of money involved at pro level, and the scholarships/infrastructure involved at college level, I find it strange that women haven't demanded a piece of the action, given the never ending debates in other sports.
In terms of physicality, women play rugby, box, do MMA etc., so I don't see a physical reason. American football must be seriously expensive to run a team, but I'm amazed that the issue of why are the boys getting all the money hasn't came up yet.
I've seen some bikini American Football games online. Big fan

Serious and non-serious answers welcome.
