I don't think it has anything to do with gender...and I speak as a member of the female contingent...but age may have something to do with some crews. The crew in the Bills game wasn't old. I think the more the league thinkers with the rules the worse it gets. They always screwed teams on holding...sometimes they'd call it, sometimes not...but PI, roughing the passer, personal fouls...are so subjective, it depends on which way the wind blows. And then you watch blatant missed calls, like the false start the Chargers got away with, and you wonder about simple competence.
