DALLAS -- Big 12 commissioner Bob Bowlsby remained resolute against expansion and a conference title game Monday at the league's media days, but he acknowledged there is some dissent among Big 12 presidents on those topics.

In his annual state of the conference address to kick off media days, Bowlsby reiterated that he believes most Big 12 presidents and athletic directors are content with the conference's current setup, specifically that there is no "critical mass" for expanding beyond 10 schools.

"It is my understanding at the present time that the majority of our presidents and chancellors believe 10 is the right number for us," Bowlsby said. "There are those that believe we should get larger, and they feel strongly about it. There are those who believe we should stay at 10, and they feel strongly about it. And there are probably four or five in the middle who are persuadable one way or the other. And I think that's exactly where we're at."

Kansas State coach Bill Snyder is a member of the contingent that believes the Big 12 needs more teams.

"I have always favored the way it was at one time," Snyder said. "I favor a 12-team conference, I favor two divisions, and I favor a championship game."

Bowlsby said decisions on expansion are entirely up to the league's presidents. He was asked about Oklahoma's David Boren declaring in June that the Big 12 is "psychologically disadvantaged" in the new playoff system without 12 teams.

"I don't believe we are at a disadvantage relative to the playoff," Bowlsby said. "I don't think one year makes a trend. We were very close to having two teams in last year. You really don't have to have much of an imagination to see how that might've worked out."

With that in mind, Bowlsby admitted that the Big 12 would likely have to reassess its plans if the conference is shut out of the College Football Playoff once again.

"If we go another year and get left out and it appears to be systemic, we need to be mindful of it," he said. "And that's why we've gone about the process of trying to get the postseason rules deregulated. We think that gives us a full array of options.

"One year doesn't make a trend. I don't believe we're disadvantaged at this point. But that doesn't mean a disadvantage couldn't develop or couldn't be shown to exist. I think it's the majority of our CEOs right now that believe likewise."

The Big 12 continues to pursue deregulation permitting a conference title game in a 10-team format, and Bowlsby said he still expects that to pass.

"Whether we end up with a championship game down the road or not, we aren't going to have one this year," Bowlsby said. "We think that full round-robin is the right way to determine it."
