For those doing historical eras, this resource is incredible.

Formations, evolution of strategy are helpful in recreating the feel of older eras.

FULL player rosters for every team and every year of the NFL up until the 90's...

FULL player roster of every player who ever played the game including statistics (linemen primarily get just a 'Games Played' line) for each year.

League standings, general statistics (points, rush/pass yardage) and top 5 or so in major statistical categories for EVERY season.

Team histories (for every team that ever existed in the NFL). Often includes ownership changes, field information.

Complete draft history.

And for those not just interested in the NFL, it has sections on the USFL, one of the WFLs (the 1971 version), and the WLAF, though these are restricted primarily to a seasonal summary, standings and playoffs...

Other things that are fun, though not necessarily helpful for MaxFB are a summary and stats of EVERY playoff game and Super Bowl in NFL history, and the 25 'greatest' non-playoff games.
