Texas’ athletic director, Mike Perrin, said this evening that he thinks this is a dialogue that could “continue several years.”Texas AD Mike Perrin on expansion: “I think this is a dialogue that could continue several years.”— David Ubben (@davidubben) June 1, 2016The conference’s commissioner has a less vague timeline.
