His praising of Utah. I have a lot of friends and neighbors who are Utah fans. They are great people, but I don't go and celebrate their team winning. Or waive a Utah flag and hope they go undefeated.
This concept seems too hard for you, but a lot of BYU fans do not care for UTAH the PROGRAM. They are fine with them losing, and they still respect a player or friend connected to the team or school. They support and for BYU and they want their football head coach to do the same. Stop praising them and wishing they win everything.
