I think they ought to do a bunch of goofy shit over the course of a weekend:
What about having a flag football game? Or have a few players play QB with a bunch of kids playing flag football.
Have players play Madden games against each other. Magnetic vibration football tournament.
A hokey-ass “skills” competition like they used to do in the '90s.
Eating competitions, bowling for charity, chili contests, go-kart racing. Get the younger fans involved with all of these.
Get creative goddammit.
