I doubt that you'd see women reaching truly elite status at most positions in the NFL due to physical differences, but there are some very impressive female athletes that have a number of desirable mental and physical traits that could be above-average in football. The best female athletes in the world compare very favorably to a large portion of players in the NFL, but they understandably make the choice to pursue a sport that they can truly be elite in rather than struggle to make the team. Because of that, it's just a matter of motivation. If you could get the best female athlete in the US to specialize in football, I have no doubt that they'd challenge for a spot on an NFL roster.
No way. Kicker is the only shot, and even then it's really unlikely.
