Athletic dept./Varsity Club. There is a Varsity Club tent in the west parking lot where there is no cost for the food or admission before home games and access to the field during pregame warm-ups. These opportunities are for former Football players. The annual Spring Football Reunion is put on by the Athletic Dept. for former players and families.
You can be as involved as you want to be. Many come to these events to reunite with former team mates. Some never come back for their own reasons. If it's attention a former player wants from BYU, that's probably not going to happen, but I can tell you former players are welcome and made to feel at home.
