Kinda like your Depression Era grandma that never threw away extra fabric and hoarded beans, the Big 12 seems to be taking all who apply because, as God as their witness, they'll never collapse again!
I guess there's only a few actual "influential" teams in college football, and it's tough to get those teams to change conferences. However, the Big 12 seems to be a giant bag of generic potato chips. Nobody really wants them, but they'll do if they're the only thing available until dinner.
The Big 12 is looking more and more like Thursday/Friday night games, with something Saturday at 11am.
