It's also equally incredible that people actually believe this. Independence has been an upgrade in every conceivable way from the MWC, the only downside that we didn't have a (weak) conference title to play for. Ben Criddle and David Nixon spoke about a previous independent schedule where Criddle asked if he would give up his MWC championship to play the schedule BYU had that year. They both emphatically said yes.
Independence was far from perfect, but to say "the season is over" after any loss is unbelievably naive. In that case "the season is over" for all but about 8 teams in CFB if they lose a single game, since the national championship is out the window.
