Link: DraftKings NFL Scoring Rules
Discovery method: Direct lookup on the DraftKings help center.
Annotation:
Summary: This page lists scoring events for NFL contests and how points are awarded.
Credibility: Official DraftKings scoring is the scoring system, so it is the baseline source.
Use in my project: I tie lineup construction rules to scoring incentives, for example how bonuses and touchdown scoring change stacking, ceiling chasing, and position value. It also supports my writeups when I explain why certain archetypes show up in winning lineups.
Limitations: It does not address ownership, contest selection, or multi entry portfolio decisions.
