Whenever the Big 12 makes a decision on expansion, the league certainly will have done its due diligence.

Big 12 commissioner Bob Bowlsby will conduct video conferences with at least 20 schools that have contacted the league about being considered as expansion candidates, sources told ESPN.

Sources also said it's "becoming less and less likely" that the league will expand to 14 teams. The most likely scenario is that the Big 12 will stay at 10 teams or only add two schools for a 12-team league with two six-team divisions, sources said.

Last month, Bowlsby and Oklahoma president David Boren said Bowlsby would be in touch with the schools that initially contacted the Big 12. The league said it hopes to make a decision on expansion by the Big 12's regularly scheduled board of directors meeting in October.

The 20 schools that will make their presentations to the Big 12 are Cincinnati, Houston, BYU, South Florida, UCF, UConn, Memphis, Colorado State, Boise State, Tulane, Temple, East Carolina, SMU, New Mexico, Northern Illinois, San Diego State, Arkansas State, Rice, UNLV and Air Force, sources said.
