Amid the growing financial success of college athletics, Big Ten commissioner Kevin Warren said he could envision the conference expanding to 20 teams and paying its student-athletes.

"I could see perpetual and future growth," Warren during an appearance on HBO's "Real Sports with Bryant Gumbel," courtesy of Angelique S. Chengelis of the Detroit News.

Warren added he's planning to have an "honest dialogue" with student-athletes about payment.
