Actually Im not. At least locally. I doubt if half the fans in this region are Bills fans. Still the Bills have had very few issues selling out a formerly 80,000+ stadium. I think you are assuming these franchises need more local support to be viable than they actually do. And its an ignorant take to assume they do, as you arent in these markets
I can tell you I’ve never met a Dallas area born fan that wasn’t a Cowboy fan.
There could be exceptions if they moved here of course bringing their fandom which is very common. Or their parents or family member who moved from another teams city who influence them.
Wagon fans normally come from areas where their team suked when they begin following NFL or whatever sport they follow.
I’m an Astro fan because DFW area didn’t have a baseball team when I was growing up. Houston was our only regional team. And they’re still my first love but I do still root for Rangers and attend some of their games.
Which brings to why do fans have to abandon their local team to root for another team? Why can’t they follow both. I have a cousin who relocated near Kansas City a few years ago. She’s still a Diehard Cowboy fan first but is now also embracing the Chiefs. That’s all good for the support of the local community.
I attended San Diego St one year chasing some California tail and started following the Chargers while still of course maintaining my Diehard Cowboys fandom.
The point is our Roots should always be where our fandom lies but doesn’t mean you’re limited to them solely. My family for 4 generations have been mostly Baylor alumni but my wife’s family are Texas. So Horns are like my second team I root for when it doesn’t interfere with Baylor. Living in the Metroplex most of my life I also follow SMU and TCU as well.
Abandoning our local team just goes against everything sports represents.
