The problem for the old Big 8 was population. There simply weren't enough viewers to make the Big 8 a viable national conference once realignment started.
Missouri was the largest "Big 8" state with about 6m in population. Colorado was next with 5.9m. Oklahoma, Kansas, Nebraska and Iowa all have less than 4m in population. There was always going to be a need to add larger states to the conference.
Texas has more population than Missouri, Colorado, Oklahoma, Kansas, Nebraska and Iowa combined. So when a TV tuned into the Big 12, even at its inception, there was roughly a 50/50 chance that TV was in Texas.
West Virginia has less than 2m in population. Again, not a lot of TV sets. That has always been a problem for the Big 8/Big 12. That's why I am not sure adding BYU helps. Sure, it has a large following amongst the Mormon church, but this isn't Notre Dame, and Utah is still a small population state.
We are kind of stuck at this point. Maybe expansion works out, but I doubt it saves us from being back at this point in another few years.
