DES MOINES, Iowa (AP) – The Big 12 has been as entertaining as any league in the country.

All that fun might come with a price.

Upsets like West Virginia beating Baylor and Kansas State surprising Oklahoma have again made the conference impossible to ignore during the regular season. But they could also leave the league out of the inaugural College Football Playoff.

Kansas State, TCU and Baylor are the only one-loss teams left, and each has plenty of challenges ahead.
