He's served on the high council in his stake, in the last few years.
He is at General Conference almost every April, and on many occasions, has taken his players to the Priesthood Session.
One of his best friends, with whom he played football at BYU, is a Director of Operations at the Conference Center. He calls KW a couple times a month. Occasionally, Whit has called the guy for tickets to various events, for his daughter. His buddy has offered to set the daughter up with VIP tickets, and KW has declined, and said "She'll sit anywhere. She's just grateful to be getting in."
Despite the CB narrative, KW is actually a very good dude- who maintains close relationships with many of his BYU teammates. He just doesn't heap praise on BYU right now, because he happens to be the HC of their archrival.
