ROSEMONT, Ill. (AP) — Big Ten commissioner Jim Delany doesn’t always agree with Mike Slive. He certainly respects him.

Slive announced this week he is retiring next summer after 13 years as SEC commissioner and plans to begin treatment for a recurrence of prostate cancer.

“Mike had a great run,” Delany said Thursday. “They dominated college football for a period of time in a way that no one else has done in the modern era. Two, I think he’s had a really good effect and impact not only on the SEC but the college community generally.”

Under Slive’s leadership, the SEC won seven consecutive BCS titles in football and 67 national championships in 15 of its 21 sponsored sports. He also helped the conference land huge television deals with CBS and ESPN and launch its own network, something the Big Ten did under Delany.

Slive and Delany also helped push for massive NCAA reforms that led to the SEC, Big Ten, Big 12, Pac-12 and Atlantic Coast Conference being able to pass legislation without the approval of other conferences.

“(The SEC and Big Ten) are two important conferences, and when they agree on things, you’re able to actually move the agenda forward,” Delany said. “A lot of the things that we’ve been able to do in the restructuring of the NCAA, the college football playoffs, are things we found common ground on which to move forward.”
