Seems to me that a three time zone conference could be of benefit in one way. The BSC can offer "full day" programming to a network.
Football:
You could have BigSky football triple headers.
Start a game at 1 pm in the Central time zone, then start a game at 3:30 pm Mountain (4:30 pm Central), and then start a game at 6:00 pm Pacific (8:00 pm Central).
Basketball:
You could probably do basketball all Saturday long ... start running games at noon Central and just keep moving west.
