BYU has not been rockin' for quite some time. Utes are getting deeper talent at every position and BYU has not really improved beyond their starters. PAC 12 has benefited them in so many ways--no real downside to that kind of inclusion.
Little Bro grew up and now makes more money than Big Bro. Big Bro needs to figure it out or hopefully find a similar financial windfall. Maybe BYU can string together some special seasons as an Indy and build something huge or somehow Big 12 will fulfill the pipedream and take the program with baggage. So maybe BYU has been unfairly excluded from the cool kids club, but they've been excluded.
Once BYU strings consecutive special seasons together, it will change everything. Can't wait! Meanwhile, the Utes still suck (because they are Utes) and it's fun to troll them.
