I don't know anyone who watches EVERY NFL game or even anywhere close to it so I don't see the big outrage over the games being offered on so many platforms. Even the exclusive games get re-broadcast on NFL Network over the following week anyway.
I don't watch all the games either, in fact 99% of what I watch is the Cowboys only. So I really only care about those 17 games plus the preseason games.
I pay for NFL+ which is fine, but if the game isn't on "live" in my market (Atlanta) I cannot watch on NFL+ until about 30-45 mins after the Cowboy games end. You actually do get ALL the games if you want them, just not all "live" as I noted. The price has been good, it's under $100 per yr.
Preseason games are broadcast live.
That said, once upon a time you could pay DirecTV and get ALL the games for one price and all in one place, and they were all live.
