NFL Game Pass has given me streaming access to all games live. Part of this is because I'm in Brazil, where there are no NFL-imposed "blackouts" of games on NFL Game Pass. In the USA, some games are blacked out live, and even for those who have the international version of NFL Game Pass in places like the UK, it's not possible to watch certain games live. But aside from market restrictions, I think in the recent pass, U.S. subscribers to NFL Game Pass were able to see Thursday-night games live, and I'm not sure if that will continue.
Through NFL Game Pass, I have access to any and all games both live with commercials and then archived without commercials after each game ends. Further, after a game has been played, I have the choice of watching the full game without commercials, a 40-minute condensed version, or a ten-minute "just the highlights" version.
I'm not sure how exclusive Amazon Prime's Thursday-night exclusivity will be. I'm hoping I'll still be able to see the games live via NFL Game Pass, as I have been in recent years. There were a couple of times that I chose to go through Amazon to watch the Thursday-night game, so I could get it with different people doing the announcing, but opening NFL Game Pass has become kind of automatic when I want to watch a game, so I usually watch that way.
I'm so positive about NFL Game Pass that I think it's important for me to say that I pay for the service and have no other relationship with it. I've just found that it's been a very worthwhile purchase for me, and I've been very satisfied with it.
