"The NFL is forbidden from doing a night game on a Friday or Saturday before the second Saturday in December, to protect the audiences at high-school playoff games and college football games till mid-December. So that means the Black Friday game would have to begin no later than 4:15 p.m. ET or so."The question you should ask is 'what are the rules?'
Sports Broadcasting Act doesn't permit all / substantial portion of a game after 6pm EST.
The game is at 3pm. Streaming is likely a red herring.
NFL's first Black Friday game will stream for free on Amazon Prime
