So there are two leagues out there with over 100 teams with one being around for over ten years, and I’ve never heard of them until now. OK, point taken.
I’m not sure where 10k at a championship game gets you. You’ve got ~5,000 people involved in playing, coaching, managing with 100 teams, so it might just be a friends and family event.
For perspective, many high school stadiums seat more than 10k and the record attendance for a high school football game is about 51k.
The attendance at some MLB games is not that much more.
I think Tampa Bay is only averaging 20k for home games this year, and it’s been lower than that in previous years.
I’m sure the regular women’s football games have attendance of more like 2K or so. A little more and they will be close to Arena football. :-)
