The SEC will have to drop its demand for all nine remaining Big 12 members to waive their rights to sue the conference and Texas A&M if it wants to admit the Aggies for membership immediately -- a step Baylor isn't ready to take, a source said Thursday. Otherwise, if the SEC sticks to its demand, then it won't get at least one member to agree -- namely, Baylor, which won't buckle until it knows what Oklahoma plans to do, a source with direct knowledge of the situation said. Oklahoma, meanwhile, has no timetable for reaching a decision on whether to stay in the Big 12 or pursue a possible move to the Pac-12, according to a source with knowledge of Oklahoma's decision-making process. Last Friday, university president David Boren said the school would evaluate all of its options. Oklahoma athletic director Joe Castiglione isn't against being part of a 16-team conference if that's the direction Boren decides, although it's not seen as ideal, the source said. The source said Oklahoma would not be divided in the process. An Oklahoma decision to remain a part of the Big 12 would offer Baylor more long-term security. A source with knowledge of Baylor's situation said the Bears' first choice is to stay together with the remaining nine Big 12 schools and pursue a 10th for expansion.
