Probably and others who would deny her as a distraction even if she could hit 50% from 60-70 yards and 80% from 50-60. Those would no doubt also call her something like a communist for upsetting the NFL's history as a male only playground.
I'm sure there would be. At the same time, there are others who are currently taking her seriously even though all she's shown is she can make a kick with no defense and a kickoff-style running start.
You're using strictly hypotheticals. Obviously teams would sign her if she's kicking at those distances. Teams are going to sign her until she shows she can take two steps and kick a 45 yarder in pads vs. A rush, with a snap, etc. I'd imagine all college kickers can hit 55 yards with a 5 yard running head start.
