The second day of Big 12 Media Days was completely upstaged by a late afternoon meeting of Big 12 presidents. The result of this meeting is that conference expansion is back on the table. To be fair, the presidents did not greenlight expansion. Rather, the conference authorized Commissioner Bob Bowlsby to "actively evaluate" potential candidates.
The media narrative has the Big 12 reacting to the recent announcement of a new television deal and conference network for the ACC, and Bowlsby suggested the ACC news did have some impact. It's equally likely, however, that an exploration--as Oklahoma's David Boren called it--was suggested by the Big 12's consultant firms, and the conference just chose this week to pull the trigger.
