Those conference numbers are what each team in those conferences get. For example, Purdue gets $54 million - not 1/14th of the quoted $54 million. In addition, the SEC just signed a new deal with ESPN, which will bump that $45 million per team total to a reported $62 million per team.
So the fact that ND does not share their $15 million with other teams means squat. They are still at the bottom of the totem pole when it comes to television money as an Independent.
