Why watch any of it? Especially if you are watching through cable or satellite, as those systems *know* what you are viewing at any given time and therefore add you to their viewer totals, which the NFL uses as evidence that “people are still watching” and to set advertising rates.
Watching as little as fifteen seconds gives them the ability to claim you as a viewer.
I am at Fort McHenry having my one-person demonstration of patriotism. While facing the flag flying high over the Fort, getting ready to accompany a beautiful YouTube rendition of the National Anthem, a four plane flyover roared above. I guess it was going to Ravens stadium....to be insulted or greeted with admiration.... I don’t know.
