IRVING, Texas (AP) — While working through the possibility of a football championship game, expansion and a league-wide television network, Big 12 presidents and chancellors say they are going to defer comments to Commissioner Bob Bowlsby. The meeting of the Big 12's board of directors came about a week after outspoken Oklahoma President David Boren again publicly raised questions about the state of the league. Boren believes those three big issues should be dealt with at the same time. After the meeting, Boren deferred to Bowlsby and Kansas State President Kirk Schulz, the board chairman. Schulz says while there are differing viewpoints, there are more similarities than differences. The league's spring meetings begin May 31.
