Even if a woman was to practice for 10-15 years, I don't know if they would ever have the leg strength to make the NFL. It is just biology.
They would be competing against men who have also been practicing for 10-15 years, and have the biological advantage geared towards kicking long distances.
But if a woman could ever reach the point of being able to consistently kick 50+ yard field goals with 65% success rate (which is around the NFL average), then I would certainly like to see a woman be on a NFL roster someday.
Agree on the biology. There was a point in Adam Vinateri's career where the punter, be it Hunter Smith, Pat MacAfee, had to handle the kickoffs because Adam wasn't consistent in getting it to the end zone. That might be a limitation for women. Then teams could turn to the punter to handle those duties. Go around to all 32 NFL teams. How many Kickers were drafted by the team they are currently on? Probably under 1/3 right now. Dan Carlsson was drafted by the Vikings but missed kicks early in his career, thus got cut and landed with LV.
NFL teams do expect kickers to hit upwards of 55 yard attempts and not see them fall 2-3 yards short.
Teams will make sacrifices for a kicker if they get consistency from them, like with Vinateri.
Kicking in the NFL is not something you can do with just 2-3 years of practice. Takes several years to be good. There are kickers who get drafted like R. Agayu who couldn't handle it. And even those in the early parts of day 3 of the draft in rounds 4-5 who don't make the team or get cut within the year.
