How FantasyOmatic defense impact works
FantasyOmatic rates every player 0–100. The defense impact for a position group is the average difference between each player's matchup-adjusted weekly rating and their opponent-neutral Player Rating — isolating how much this week's specific defense helps or hurts that position. Defensive efficiency allowed is the average fantasy points per touch the opponent gives up.
- Positive adjustment — the defense is a favorable matchup; expect boosted production.
- Negative adjustment — the defense is tough; expect suppressed production.
- Per-position — QB, RB, WR and TE are rated separately, since defenses differ by position.
