I get most of my NFL gossip from /r/nfl on reddit. They have some random predictions which are quite well written compared to other media, and they post all the relevant news on there too obviously. I like SBNation but I don't usually subscribe to it unless I get linked to it. The Chargers one seems pretty good.
For stats I like Advanced NFL Analytics and Rotoviz (which is a pay site but costs like 5 bucks for the off season). For analysis I like mattwaldmanrsp, Ben Muth on Football Outsiders, Matt Bowen on Bleacher Report, smartfootball and probably some others. I also listen to the Ross Tucker Football Podcast. Between all that I never bother clicking on nfl.com unless I feel like deliberately disappointing myself.
