I think it's an interesting concept and thinking outside the boxNah… Some are too busy trying engage others into a Johnson measuring contest putting others down instead of having mature conversations.
To your point, there’s some who may want to check out the OL drills. Or WR/DB, 7 v 7 battles on Wednesdays. Or some who probably can’t make it on Saturdays so he’d plop down a 10/ 20 for practice. Kids may get into practice being up close (as close as up close can be for practices).
It’s an interesting idea and if you can set up bleachers on the perimeter like at the Giants Stadium practice facilities… maybe:
What bothers most people is the idea of paying for things on a one off instead of all at once
E.G., if you buy season tickets and a portion went towards NIL and another portion of the cost went towards watching an open practice, nobody would care
In regard to Boosters, if you donate enough money, you get certain perks
Personally, I just love football and the chance to watch a practice for $50.00 is something I would do in a heartbeat
