What do the grey areas mean?
Welcome to the world of blackout rules. The short answer is: no game at all. This can be due to one of two rules: a) no games can air at the same time as a local team’s home game on another network, or b) if a game is blacked out because it doesn’t sell out, the network with the doubleheader can only show one game. Don’t shoot the messenger, I think the rules are stupid too.

Preach it, brother. I’m glad the Redskins have improved to the point that they will have some prime-time games, because that means no blackout on Sunday.
