I agree that nobody will care about SMU playing ACC schools. But, that is not my point.
Historically, in the linear channel cable bundle model, the conference networks get 2 rates: in market and out of market. For example, Rutgers is in the NYC media market so NYC pays the in market rate for the Big 10 Network. It is assumed that SMU, since it is in the Dallas/Forth Worth market, would bring the ACCN the in-market rate. The difference between the 2 rates could be $1/month per subscriber. So, adding SMU could add up to $3 million per month. or $36 million per year to the ACC Network in subscriber fees.
