Usually dependable: https://www.reddit.com/r/nflstreams/ Dependable, but sometimes craps out in the 2nd half of games (real HD): https://blabseal.org/frodo/ X out of ads, do not click anything that says you need a download. They lie. http://www.myfeed4u.com/section/american-football/

Reddit.com/r/nflstreams is absolute money for me when I'm at school. I use buffstreams and never have an issue and it's awesome quality.
I use the NFL package that post the full game the following day. Monday is football day for me now most of the time. It provides condensed games which show every play and are about 40 minutes, the full game with commentary and no commercials, and the all 22 version. Well worth the $79 for the year.
