Clay Travis just put out an article about the SEC going to 14 teams. He explains the economics, including why TAMU and Mizzou make so much sense. He also walks through the economics of BTN and provides projections (Kagan) of $333 million, or over $27 million per school, per year for BTN by 2015.* It is a very good article for anyone who is interested.
* The P12 just negotiated a new deal with ESPN and FOX for its tier 1 and 2 TV rights. That deal is north of $20 million per school per year. The B10's deals with ABC/ESPN and CBS come up for renewal in 2015/2016. Assuming a similar increase, it is likely the B10 will be generating more than $30 million per year from third party TV rights upon renewal. That will be in addition to the $27 million per school generated by BTN.
