If DirecTV is completely shut out of Sunday Ticket, I hope they will offer the Red Zone channel. For some people I know who have had Sunday Ticket in the past, but left DirecTV, they have found RZC a pretty good replacement.
I know some people have stated they were able to get RZC on DirecTV without Sunday Ticket but it is not too simple from what I have seen posted.
For those complaining about lack of broadband, don't blame the NFL. The government has poured billions into expanding broadband with pretty poor results. The NFL, or Netflix, or MLB is under zero obligation to ensure each home is served by an adequate connection to receive their programming.
