I enjoy hearing both sides of the story. I know series get cancelled all the time for various reasons, but it usually happens at least a calendar year before the game is to be played. I can understand why some would speculate Nebraska might be following the Indiana method of getting a playoff bid.
The B1G plays 9 conference games and they want the SEC to go to 9 games as well. The SEC coaches and General Managers don't want to do that. So the B1G may send the memo to the SEC that the B1G will just schedule an extra cupcake instead of an SEC opponent. Getting to the playoffs is and should be the ultimate goal of Nebraska.
