Plug in your favorite team(s) and the free NFL Now app presents content customized to your tastes. There's also a "most popular" option which presents a stream of content, and is rather like watching NFL Network.
I found this excerpt from the linked article interesting:
"For the truly football-obsessed, there’s the NFL Now Plus option, priced at $1.99 monthly in the U.S. with international rates varying. Subscribers will get instant in-game highlights from each game (in the free version of the service, these will be delayed), as well as a customized stream of big plays by their favorite team, players or fantasy roster."
The "instant in-game highlights" on Sundays sounds a lot like NFL RedZone but more targeted to your favorite team(s), and for just $1.99/month. I'm a cable cutter so I'm going to have to check this out.
No live games, however.
