I don't want to lose the NFL Network either but there was so much conjecture here that I thought I'd look for some facts:
Cable and Satellite Television Network Tiering and a la Carte
Pretty wordy government gibberish but there are some interesting facts. "James Robbins, chief executive of Cox Cable, reportedly stated at a Goldman Sachs investors conference that ESPN accounted for 4% of Cox subscribers’ viewing, but 18% of Cox programming costs."
Cable's Pricey Ticket
"Sports networks are the most expensive programming on basic cable. The license fees for all the networks on an 80-channel basic-cable package cost an operator around $12 per subscriber last year, Morgan Stanley estimates. Nearly half of that stems from just a handful of programming networks: ESPN (around $3 monthly), at least one regional sports network (around $2), and smaller channels like ESPN2, ESPNews, ESPN Desportes (another 35¢ cents for the package)."
"By comparison, the license fee for other basic-cable networks can be just pennies per subscriber; some networks, such as MTV or TBS, commonly run 25¢-50¢. (Disney Channel, however, gets $1 per sub.)"
"New networks will only add to that. The NFL Network wants 75¢ per subscriber."
