Jim Delany announced yesterday that he will be stepping down as Big Ten commissioner after the next academic year, in June 2020. Over the past 30 years, Delany’s name has become synonymous with the Big Ten conference, and imagining a Big Ten without Delany is very tough. In addition, Delany has become one of the most powerful people in all of college athletics during this time — his ideas helped to shape the huge money-making business that college athletics is today. Delany has been a visionary, but he’s also had enough missteps that he leaves a mixed legacy behind, and that it might be time for new blood atop the conference.
