The Big Ten hasn't won a national championship in football since 2002, when Ohio State beat Miami in the Fiesta Bowl. It's been even longer since the midwestern conference took home a title in basketball; Michigan State won it all in 2000. But the conference does seem to know how to make money, and they do it better than anyone else.
A report in the Journal & Courier states that the Big Ten predicts that its revenues will continue to grow each year, and that by 2017-18--once the conference's new TV deal is signed--12 of its 14 teams will make roughly $45 million in revenue.
The Big Ten schools that won't make the full amount are Maryland and Rutgers, who both join the conference this upcoming school year. They, like Nebraska has to, need to spend six years in the conference before getting a full share.
The conference projects that 11 schools will pull in $27 million this year, $30.9 million in 2014-15, $34.1 million in 2015-16 and $35.5 million in 2016-17. Nebraska gets its full share in 2017-18.
