to them how someone like me, a member of the church of Jesus Christ of Latter-day Saints(just practicing) from California has absolutely no ties to the University of Utah. But I am LDS, and wanted to come to my church's school and be around other LDS members. They were like, "I've never thought about it that way before."
I think some fans grow up and just get caught up with the mormon's in Utah choosing between byu and utah that they forget BYU isn't a state school. Half the school and fans are not from Utah and therefore have no reason to be associated with Utah football.
