Justice department questioning college football's no-playoff system

The U.S. Justice Department is now asking the NCAA the same question fans have been asking for years: Why doesn't college football have a playoff system?

Assistant Attorney General Christine Varney has written a letter to the President of the NCAA. In it, Varney writes "serious questions continue to arise suggesting that the current BCS system may not be conducted consistent with the competition principles expressed in federal anti-trust laws."

CNN's Kiran Chetry and Christine Romans speak with "Sports Illustrated" senior writer Stewart Mandel about the inquiry.
