You should be able to watch games on NBC Sports Washington. ESPN+ is for out of towners.
It's a national TV game. There have always been national games that weren't on the local channel. I don't love having to pay an extra $7, but in the scheme of things, not a big deal. I'll cancel it after this game, reactivate it for December (two such games then), probably keep it for January (one such game), and then cancel it again.
