If Bronco and 8-5 seasons is the ceiling for BYU with Independence than you are right. We need to change our expectations quite a bit.
Obvioisly we will never be a Bama or USC, but as a lifelong fan I want and expect more for BYU football. Maybe my expectations are outdated and I need to start investing my time and money in a serious program.
But I think with the right man in charge, BYU could be as competitive as Boise, who smothered the 2nd best team in the PAC-12 and won yet another BCS/NY6 bowl game.
