I'm in Lancaster, PA and get Lancaster and Harrisburg channels, but I think our markets are the same. Minus the 4 prime time contests (Mon Nt and ESPN SUn) I bet you get 6 of the remaining games. At Baltimore definitely, but as for the rest it depends on who the Ravens and Steelers play and at what time(that whole double-header thing) You'll probably get the at NYJets game and the Steelers game, if Baltimore isn't playing at the same time. You'll get a lot of crappy games there- Bengals, Browns, Ravens, Steelers on CBS all the time and on Fox Washington, Philadelphia and for some reason Dallas a lot.
I know it's easy to say get the satellite and get the ticket, but seriously if you want to watch the Fins it's the way to go. I got Direct TV with Tivo, and just last week my local channels came onto my satellite(Direct TV is giving them to me FREE for 6 months- they do treat their long-time customers well). TIVO right now is $99 for the receiver INSTALLED. If you can, look into it. I'm getting a 2nd TIVO installed on Monday
