Big 10 = 14 expansion was all about the $$$$$$. Cable companies in the NYC and Washington DC/Baltimore metro areas now carry the Big 10 = 14 network as part of the basic package. The fee is $12 a year in those markets. Some have calculated the expansion brings in almost $50 MM a year. As someone who grew up in the NYC metro area nobody cares about Rutgers football.
