If Texas A&M leaves the Big 12, options for OU and OSU:
Remain in the Big 12: A nine-team conference is not appealing, at least to OU officials. But replacing A&M would be a sign of stability. Even better would be bringing in three schools and returning to divisional play and a football championship game. Arkansas and Notre Dame are pipe dreams for an unstable conference. Viable options include Brigham Young, Air Force, TCU and Louisville. Chances: 50 percent OU, 50 percent OSU.
Join the Pac-12: This option almost certainly will be available for OU and probably will be available for OSU. The Sooners would need the Cowboys out West, not just for political reasons, but because any school from this part of the country joining the Pac-12 needs to be part of a four-team group, to allow for the Pac-16 model of two divisions. The East Division would include minimal games on the West Coast in all sports. The Pac-12 has stated its intentions on expansion, and OU and Texas remain the two biggest prizes. Chances: 45 percent OU, 40 percent OSU.
Join the SEC: OU and OSU have been mentioned as possible candidates, but OU has not expressed interest, even declining an invitation a year ago from the SEC. OSU is a long shot, unless the SEC expanded to 16 teams and needed a school from the Southwest. Chances: 3 percent for OU, 2 percent for OSU.
Join the Big Ten: OU would prefer to go West but would consider the Big Ten. But would the Big Ten consider OU? The Big Ten would not consider OSU. Chances: 2 percent for OU.
Join the Big East: If OU goes somewhere without OSU, the Big East could be a fallback for the Cowboys. The Big East has established a Southwest embassy with TCU and might be interested in splitting off into football and non-football divisions, with ex-Big 12 members supplying some football prowess. Chances: 7 percent for OSU.
Join a Longhorn Conference: If OU goes somewhere without OSU and Texas, the Longhorns could patch together remnants of the Big 12 with BYU, and UT athletic director DeLoss Dodds has even talked about Notre Dame. Chances: 1 percent for OSU.
