I'm not saying every Bills fan in this area doesn't have a dish/Sunday Ticket, but there are enough around here that don't have it and don't want to.
And for the most part, we don't see the Bills unless they're playing the Jets. Even if they're playing the Pats*, there's no guarantee. The Seattle game was an exception because it was on Fox and the Giants had already played the Thursday game.
The Jets & Giants are king around here....and there are a number of games later in the season where the Jets & Bills conflict (i.e., play at the same time on the same network), so with the Favre lovefest going on all year long, there's no way in Hades we're going to see the Bills those weeks.
