It's not called NFL Rewind anymore. It's called NFL Game Pass now, and there is a different one for outside of the U.S. (which has it live).
The U.S. one is more now...the NFL is a money-monster. I'm pretty sure it's $100, and you can watch ANY game after the fact going back something like 4-5 years. Other good features too, like watching ONLY the plays and relevant action, excluding all the down-time...that takes about a half-hour or so.
Like others have said, there is a free 7-day trial.
I'm going to sign up for this soon and keep it if as advertised. Funny how they seem to do their best to hide the information you really want to know when you go to the site. I seem to have found, after MUCH searching, that you can access the 1 o'clock games after the 4 o'clock ones are over this year...although the guy on the phone told me something different (I think that guy was wrong). I don't think you can watch anything on Game Pass while Monday Night games are in progress, maybe Sunday Night games too.
