Man, could fully lean into this "Krewe" idea and have a Mardi Gras Ball that's also a fundraiser. That'd be a good time. Think a lot more people would buy into the idea of joining a Krewe in the traditional sense if there was a Mardi Gras Ball they could attend with fellow alums/fans that are uneasy about NIL.
And if the Krewe is loosely affiliated with the University/Athletic Dept, could use indoor practice facility or another facility for a lower cost event space. I'd join for that for sure.
It would be a lot easier to pitch the Krewe to my friends as access to a University-affiliated Mardi Gras Ball than a collective for NIL.
