This ends up being a pretty simple argument. If you are a football fan, you want the NFL to win this argument. The cable companies routinely place content in which they have an ownership interest in the basic tier because it brings in more advertising revenue. The NFL wants the same for the NFLN. Since the NFL exclusively owns the NFLN, the cable providers do not have an ownership interest and want to place the NFLN in a "sports tier" so people will pay them more for the privilege to watch it. This action also drastically reduces the audience and the advertising revenue to the NFL for the NFLN.
Therein lies the argument. The NFL accuses the cable providers of maintaining a double standard for programming and has been insisting on inclusion in the basic tier in their negotiations. At the same time the NFL is insisting on a fairly high rate payment by the cable providers for the rights to carry the NFLN. Some cable providers maintain that they control where programming goes and will not accept the NFL's terms.
Things will probably take a dramatic turn next week when many people realize they are not going to be able to watch the GB vs Dallas game. There will be a hue and cry at that time.
If you like football and want all of those "non-football fans" to help you pay for the service then you want the NFL to win. If you hate football, you want the cable providers to win and have all of those tacky football fans pay for the privilege of watching their silly game.
