FWIW, I don’t think they’re useless in a huge stadium. Mascots aren’t. Especially when there can be so much time between plays. But I think old school athleticism and common sense outfits would bring back the fun. If folks want pole dancing, they can hit the local strip club.
Yes.
But seriously, cheer leading was meant to rouse the fans DURING plays, and in huge stadium you can’t see them. Pointless to just have them doing halftime shows.
Leave them to high school where they are visible.
