I also just want to add this completely anecdotally, but I had three instances that stood out to me in my personal life.
1. When I was on dating apps, I had several girls match with me in Travis Kelce jerseys. When I asked about their NFL fandom because that's something obviously big in my life, they responded that they were only into football because of Taylor Swift. I talked to a few girls who said they only watched games to see Taylor Swift.
2. On the same apps, I once came across a profile that had a prompt that read, "Do you agree or disagree that Taylor Swift made Travis Kelce famous?" That one actually really made me mad to read.
3. I was at a restaurant the other week and a girl was eating with her family and she commented something along the lines of, "We've never really seen NFL celebrity couples like this. Taylor Swift is like the first big celebrity to date an athlete." It's blatantly false, but this was someone who probably literally never paid attention to sports until Taylor Swift.
Again, I'm not saying the NFL is definitely rigging games, but I think it'd be very naïve to think it's not a possibility. Women are getting into the NFL, and A LOT of them, in ways that the NFL hasn't seen before thanks to Taylor Swift. The NFL's goal is to make and maximize profits. It's doing them a lot of heavy lifting and good to have Taylor Swift on screen during games.
