After some searching, I found out via the506.com and nfl network's schedule, the nfl network will show some classic games. I'm not talking about games from 2 yrs. ago or this past season. The majority of the games are old games. This is something you shouldn't miss. I put the link below. It's the nflnetwork page with all the info. Enjoy!!
