The preseason stuff is really good. Once the season begins the content really tails off...but the weekly IDP roundtable is some good stuff and I like how it is structured by position group (just too late in the week for waiver pickups).
Mainly I just monitor box scores and snap counts and do Google searches on emerging players then read stuff from that player's local media.
Where FBG content was extremely helpful was when I was first getting up the IDP learning curve back in the day (schemes, stat crews, matchup plays, etc.).
