Glossary every stat on this site, in plain English; hover any column header for the same definitions

Snap %: Share of the team's offensive snaps the player was on the field for. The leading indicator of role size: snap share moves before production does.
Target share (Tgt%): Player targets divided by team targets. One of the stickiest, most predictive volume stats for PPR scoring.
Air yards share (AY%): The player's share of the team's total air yards (the distance passes travel toward him). Captures intended downfield volume, and it is stickier than receiving yards.
aDOT: Average Depth Of Target: air yards per target. Describes role: low = short/slot work, high = downfield shots. Not better or worse, just different volatility.
WOPR: Weighted Opportunity Rating = 1.5 × target share + 0.7 × air-yards share. Combines the two stickiest receiving-volume signals; ≥0.6 is elite territory.
Targets/gm (Tgt): Passes thrown the player's way per game. In PPR, a target is worth roughly 1.6 points of expectation, so volume is king.
Receptions/gm (Rec): Catches per game. Each is a full point in PPR scoring before any yardage.
Receiving yards/gm: Receiving yards per game.
Carries/gm (Car): Rush attempts per game. A carry carries about 0.6 points of PPR expectation, less than half a target's value.
Rushing yards/gm: Rushing yards per game.
xFP/gm: Expected fantasy points from opportunity alone: 1.6 per target + 0.6 per carry (league-average values). Compare with actual points; big gaps usually close.
Pts/gm: Actual fantasy points per game under the scoring format selected in the header (PPR / half / standard, 4- or 6-pt passing TD).
RZ touches/gm: Red-Zone touches per game: carries plus targets inside the opponent's 20-yard line. Predicts future touchdowns better than past touchdowns do.
RZ carries/gm: Carries snapped inside the opponent's 20-yard line, per game. Goal-line role is the biggest driver of RB touchdown expectation.
RZ targets/gm: Targets thrown inside the opponent's 20-yard line, per game.
End-zone tgt/gm: Passes thrown INTO the end zone for this player, per game (air yards ≥ yards to goal). The sharpest touchdown-opportunity signal, but small samples, so expect noise.
Pass att/gm: Pass attempts per game: raw QB throw volume.
Pass yds/gm: Passing yards per game.
Comp/gm: Completions per game.
Sacks taken/gm: Times sacked per game. Sacks end drives and drain fantasy points, so pressure volume matters.
Pass EPA/gm: Expected Points Added on pass plays, per game, the best single QB efficiency number (accounts for down, distance and field position).
QB hits/gm: Times hit while throwing, per game (from play-by-play). Sustained punishment predicts decline and injury risk.
YAC/gm: Yards After Catch per game: production created after the ball arrives.
Games (G): Games with at least one touch or pass attempt in the selected span.
Pts total: Total fantasy points over the span (not per game), under the selected scoring format.
Scoring rules: Every points column is computed from raw stats under the header's scoring selectors. Receiving: 1 / 0.5 / 0 per catch (Full / Half / No PPR) + 0.1 per yard + 6 per TD. Rushing: 0.1 per yard + 6 per TD. Passing (QB): 0.04 per yard (1 pt per 25), 4 or 6 points per passing TD per the selector, −2 per interception. All: −2 per fumble lost, +2 per two-point conversion.
TPRR: Targets Per Route Run, the best per-play measure of target earning. Needs charted routes data, which has no reliable free weekly source yet; shown as pending.
Provisional: Same-evening numbers from box scores, minutes after games end. Replaced by cleaned official stats overnight (and corrected again by Thursday).
Partial week: The NFL schedule says this week still has unplayed games, e.g. “1/16 games” after the Thursday game. Stats shown are only from completed games.
WC / DIV / CON / SB: Playoff rounds: Wild Card, Divisional, Conference championship, Super Bowl. Playoff weeks are numbered 19+.
