From ute board:

"I know the Leavitt family personally. There’s no love lost between Dallin and BYU fans. He famously taunted them one year when Utah state smacked BYU. But oddly enough he’s said multiple times he’d like to coach at BYU, so it’s not the athletic program he has a problem with as he stated in the video"

Dizzying logic, maybe makes sense to cow fans though
