There are only 3 providers that are Big enough to Bid on NFL ST Comcast, Dish and Directv.
If cable ever got the chance to bid on it in the USA, it would likley be Sports iNDemand handling it, which is run by Comcast, Time Warner and Cox.
However viewers would likely be pissed with their version of blackouts. They can't do it on the market level like DirecTV, they handle blackouts based on the headend level, and every team that has territory in a system served by the headend has to be blacked out. For suburban and rural cable systems on the outskirts of a market, their headend could be serving systems in multiple markets. i.e. here in the Poconos the headend used by Blue Ridge serves systems that are part of the NYC, Philly, Scranton, and Harrisburg markets. Every system served by that headend gets blacked out of Phillies, Mets, Yankees, Pirates, Nets, Knicks, 76ers, Devils, Rangers, Islanders, Flyers and Penguins, even though MSG and Root Sports Pittsburgh aren't carried on all of their systems.
If they were to take Sunday Ticket, their systems will always be blacked out of the Giants, Jets, Eagles, Steelers and sometimes the Ravens depending on what the Harrisburg stations choose, even if the system you reside in doesn't carry all of those Fox and CBS affiliates as neighboring stations.
