CHICAGO — Big Ten commissioner Tony Petitti overwhelmingly embraced the on-field rivalry his conference has with the SEC, but he stopped short of committing toward breaking away from the NCAA should Congress fail to pass a Protect College Sports Act, unlike SEC counterpart Greg Sankey.Petitti, who spoke for nearly 45 minutes Tuesday morning to open the three-day Big Ten media days event, instead focused on working with the SEC and other power conferences to provide a system more palatable to all entities, rather than striking out alone.“Breakaway is … a word that creates a lot of emotion,” Petitti said. “I’ve never heard that anybody doesn’t want to play anybody else. We want to schedule more good games against teams that our fans expect. We’ve just got to get to a system that allows us to do that.“I think every league is going to be in a position to say, what are we going to do that’s better than what we have now, and do we have to do it ourselves?”At SEC media days last week in Tampa, Fla., Sankey said breakaway conversations are “real” and “I do not believe that is a leverage point.” Sankey reiterated later, like Petitti, that he prefers not to reach that point, but frustration over being unable to enforce the NCAA’s rules has bubbled over among SEC administrators. It’s similar for Big Ten brass, but the rhetoric is more measured publicly.
