Random idea that just came to me.. And maybe BYU already does something like this but maybe not..
What if BYU did some sort of fan convention kind of similar to Comic Cons but instead of actors you have BYU players, coaches, etc. past and present show up and you can have sessions where you can "Ask the coach" or a player or do some sort of activity.
I know that BYU does events like meet and greets and stuff with the current coaches and players but never heard of a massive event with both current and past players. IDK maybe you could have all of BYU sports Football, Basketball, Track & Field, Cross Country.
