I'm a Utah fan that donates money to BYU and has season tickets:) I'm not Mormon and love Kalani. I got to sit with Kalani at multiple recruiting recap dinners at the UoU. I personally have known 3 BYU (the stories they tell) players in the last 8 years. I give my season tickets away most the time, but still think I support BYU more than most BYU fans.
Life boring if you go to church with the same people, live in the same place, hang around people that only exactly match your lifestyle, and only fans of your own school.
