If byu was still undefeated, the game would have started around 1:30 which is kind of a dead time from the 10am start and the primetime night start times. Since they are on a free fall, espn can air them at the late 8:30 start time and they will still get tolerable ratings because byu has a better following than any other mwc team or a crappy PAC12 game (which are the other teams that they would air at that same time)
