You're very lucky, @Swaye. If she has any athletic talent at all, she'll get a scholly somewhere, thanks to Title IX.
Your first job is to teach her that fat women are gross pigs, no matter what they wear and what she sees on TV, and a healthy body is not 300 lbs., plus. Immunize her against that horrendous Body Positivity bullshit as early as you possibly can.
Women Johnny try hards that are competitive women but lack athleticism have a better shot at a scholly than a male would.
If you’re a girl and your dad works on your jumpshot with you from a young age(really a set shot), that girl can get a scholly for hoops when a male that can shoot but has no athleticism won’t get very far.
The sheer numbers favor women too. More males play sports as kids, so if you’re a girl really into sports and in a competitive atmosphere, chances are you can play college ball somewhere.
