I'm from Connecticut, so I get all the Jets/Giants/Patriots games. I've gotten really good at looking at the schedule and figuring out whether we're going to get the game. Last season, we had 14/16 Cowboys games. The season before, we had 15/16, the same as the season before that.
As long as FOX has the doubleheader, we will get Dallas@Tampa.
Basically, the way it seems to work.. I get those 3 games, no matter what. 95% of the time, one of them has a SNF or MNF game. If for some reason the Jets/Patriots play the same time, they will bump the Jets for the Patriots.
After that, they seem to centralize around NFC East/AFC East games. I think it's the assumption that you'd want to watch other teams in your division. They will toss us the Dolphins or Bills if there's an open slot on CBS, and they'll give us Eagles/Commanders/Cowboys. Thing is, I don't think I've missed a divisional game yet. Cowboys vs. anyone in the NFC East will always get played over the 4th member of the NFC East's game.
The only time I run into problems is when the Giants have a 1:00/4:15 PM game, the same as the Cowboys. But it really does seem like the planning committee tries its best to avoid that.
