BYU - Wow, we're so bad we didn't even make a bowl game? Let's see where we went wrong, improve it, weather the poor recruiting, and go 9-0 to start the next season
Utah - Wow, we're so good we're going to dominate this truckstop conference. Oops, we're 1-5 with a loss to BYU on our home field. Time to burn everything down in tantrums of various sorts, foster a culture where our fans assault people and litter our own field, and where our admin burns the conference that gave us a second life just to make us somehow feel better. And now our players are transferring out, fights in the locker room, national scorn heaped upon us on way to becoming the most hated program in the country.
That program is a BYU parasite whose self esteem is linked to proving BYU isn't good. As a result, it has no introspection, which leads to not improving which leads to more losing and proving they're STILL inferior to BYU in every way its fans want it not to be.
