It’s not a certainty that YES Network will go dark on Comcast systems in New Jersey and Connecticut at midnight tonight when the latest extension to its current carriage deal expires, but consider this: YES Network already filed a complaint with the F.C.C. on Sunday night alleging that the cable operator wants to put it on “the Siberia of a tier.” And yesterday, while the Yankees’ Tim Hill was striking out the Brewers’ Jake Bauers in the top of the sixth, viewers heard the voice of YES president and C.E.O. Jon Litner warning of an expected blackout and accusing Comcast of “bullying” in negotiations. His rant lasted a solid three and a half minutes.
