The voice of reason, backed by actual statistics or other citations other than emotion, strikes again.
I'm in DC also Scrib, and the reference you talk about, refers to HOME games only. So when the Skins are at home at 1:00, and the Bills are in Baltimore, also at 1:00, for example, Skins get exclusive status.
Now, the last couple of years, there's been talk down here of making the DC-Baltimore area a single NFL market, like NY. So, if the Skins kick off at 1:00, the Ravens would go at 4:00, etc., etc. The reason being, is that there are many Ravens fans in the Maryland suburbs that are in the DC TV market. In fact, as you noticed last year, Ravans at Bills was shown on local DC ch. 9, while the Skins played at home. There was a waiver for last year (and this year too) that all Ravens road games be shown in DC, whether or not the Skins are at home. Many Ravens season ticket holders were upset they couldn't see their team on the road.
