If you can't get NFL Network, try here after kickoff:

Click the game you want then click the "play" arrow in the big box. Ignore the malware warnings from your browser. They used to cover the box with an ad and you had to wait 30 seconds before trying. The ad isn't there anymore but, to be safe, click only the window.
Ready to be served some Famous Jameis Tasty Turnovers.
