Block	Column	Formula	What it tells you
Opportunity	Snaps	offensive snaps	From Pro Football Reference's game snap counts.
Snap %	= Snaps / Tm plays	Tm plays is the most snaps any one player on the team took that game, which is always a lineman.

What it tells you

Opportunity

Snaps

offensive snaps

From Pro Football Reference's game snap counts.

Snap %

= Snaps / Tm plays

Tm plays is the most snaps any one player on the team took that game, which is always a lineman.

TGT %

= TGT / Tm TGT

Share of the team's targets.

ATT %

= ATT / Tm ATT

Share of the team's carries. The quarterback's carries are in the denominator, so a back's share is of the real total.

INVL

= (TGT + ATT) / Snaps

Involvement: how often a snap turned into the ball in his hands.

USG

= (TGT + ATT) / (Tm TGT + Tm ATT)

Usage: his share of everything the offense did with the ball. The single best one-number view of a role.

DELTA

= USG − AVG(USG)

Points above or below his own average, see below.

(hover)

AVG and league avg

Every share cell carries his average and the position's league average; hover or tap to see them.

Production

RuYd, Ru %

= RuYd / Tm RuYd

Share of the team's rushing yards.

ReYd, Re %

= ReYd / Tm ReYd

Share of the team's receiving yards.

AirYd, Air %

= AirYd / Tm AirYd

Share of the team's air yards: how far the ball travelled on his targets, caught or not.

RACR

= ReYd / AirYd

Above 1 means yards after the catch outran the throw.

WOPR

= 1.5 × TGT % + 0.7 × Air %

Weighted opportunity, Josh Hermsmeyer's formula.

rushing + receiving TD

TD %

= TD / Tm TD

Share of the team's rushing plus receiving touchdowns.

DOM

= (Yards share + TD %) / 2

Dominator. Yards share is his share of the team's scrimmage yards.

DELTA

= DOM − AVG(DOM)

Results

PPR, PPR %

= PPR / Tm PPR

His share of the team's fantasy points at RB, WR and TE. Quarterbacks are left out so the share says something about the skill group.

0.5PPR, 0.5PPR %

= 0.5PPR / Tm 0.5PPR

The same in half-PPR.

STD, STD %

= STD / Tm STD

The same in standard scoring.

DELTA

= PPR % − AVG(PPR %)

Setting	Value	Why
AVG	mean of his previous 4 played games	A bye or a missed game is skipped, not counted as zero, so a returning player is measured against games he actually played. Week 1 has no average.
DELTA	this week − AVG, in points	Green above, red below. Bold from 8 points either way.
League avg	mean of every player at the position with ≥ 1 snap that week	A low bar on purpose: it reads as "an ordinary player at the position", not "a starter".
Green scale	4 steps by size of the share	Snap %: 30, 50, 70, 85. Shares: 5, 15, 25, 35. WOPR: .20, .35, .50, .65. RACR: .5, 1, 1.5, 2.
Sort	click a heading	Whole league, highest first; again for ascending; a third time back to teams.
Published	Monday or Tuesday morning	Checked from Monday morning, and published only once every game of the week is final and in the data — so a week with no Monday night game lands Monday, and the rest land Tuesday. Wednesday's rebuild picks up stat corrections.

Value

Why

AVG

mean of his previous 4 played games

A bye or a missed game is skipped, not counted as zero, so a returning player is measured against games he actually played. Week 1 has no average.

DELTA

this week − AVG, in points

Green above, red below. Bold from 8 points either way.

League avg

mean of every player at the position with ≥ 1 snap that week

A low bar on purpose: it reads as "an ordinary player at the position", not "a starter".

Green scale

4 steps by size of the share

Snap %: 30, 50, 70, 85. Shares: 5, 15, 25, 35. WOPR: .20, .35, .50, .65. RACR: .5, 1, 1.5, 2.
