Yes. The NFL Sunday Ticket is DirecTV's crown jewel. I however prefer DishNetwork, primarily for their far more flexible offerings of equipment (such as dual tuner units that can be independently fed to different TV displays). It's like two boxes for the cost of one (One output is HD, the second SD but I still have numerous SD TV's to this work fabulously). DirecTV can record one channel and display another, but cannot send different channels to two different TV's).
If DTV would offer this, I'd leave DishNetwork but alas, DTV even killed off independents from making and selling receivers for DTV. In the past, I loved some of the old Hughes boxes, which were far superior to the DTV offerings.
Yet I still hedge my bets as I'm a grandfathered NFL Sunday Ticket/Superfan only subscriber as well (DTV).
