Let's say Nebraska and Missouri leave the Big 12 for the Big 10. Texas, Texas A&M, Texas Tech, Oklahoma, Oklahoma State, and Colorado then follow suit and leave for the Pac-10. Now what? Well, Kansas, Kansas State, Iowa State, and Baylor, first of all, I can assure you that the sun will rise the next day, and when it does rise here is the plan for you.
The Big 12 leftovers will be in a favorable situation, for being leftovers. Being positioned in the middle of the country, they have the option now of picking and choosing from the strong schools on the west and east of them. Take your time, because you will have time, and look at the following candidates.
Mountain West (MWC)
Air Force, BYU, TCU, and Utah
Houston, SMU, Southern Mississippi, and Tulsa
These schools provide two key ingredients: 1) An expanded conference footprint, while maintaining the traditional Big 12 footprint, and 2) A conference that could still be an automatic qualifyier in the BCS. You can pick your size, anywhere from 9 to 12 teams (5-8 in addition to the four leftovers). Here are some scenarios:
TCU or SMU
BYU or Utah
As long as you take TCU over SMU, this conference should be stong enough for a BCS AQ. The only problem is that long term, SMU might be better at getting attention in Dallas/Ft. Worth and Texas in general. :
TCU or SMU
This will give you 12 teams to hold a championship game. You are taking a chance on BCS AQ status with Louisville, but the basketball showdowns with Kansas could be too irresistable. Hopefully with both BYU and Utah, the conference will be strong enough to get AQ status.
The moral of this post is to keep your heads high Jayhawks, Wildcats, Bears, and Cyclones. The Big 12 has a future, and it might not be all that bad.
