Perhaps the Big12 is sitting on their hands and not worried about a conference championship game yet is because of BYU. We aren't going anywhere soon. With us they get bigger value than the PAC got for Utah or the Big 12 got with TCU. They will get a program that travels well and will automatically be in the top 3 in Football and Basketball attendance. They will also get the SLC market and a decent dent into the Las Vegas and Phoenix market. Utah and TCU weren't even close to the numbers that BYU has as they were literally just a number for the conference.
So the Big12 has the luxury to wait and play their 10 team league this season.....they have BYU on standby to prop them up if needs be.
