Last I read, BTN gets $6.00 per year per cable/satellite subscription. Adding Rutgers and Maryland to the footprint puts BTN on the base package of all cable/satellite subscriptions in those highly populous areas. Go to Nielsen and look at the number of TV households and multiply by $6.

Like it or not, the Maryland and Rutgers markets add huge $$$ to the BTN coffers which translates to better revenue for all B1G schools. Hell, between NYC and D.C., there are 10 million TV households. Des Moines' market brings 433,000.
Overreach? Hardly. Massive successful cash grab and that is what it was all about. Iowa's athletic coffers have never been more full and that has a lot to do with expansion.
