Box score totals from ESPN (regular season and playoffs; “last 4” is each player's four most recent games with a box score line). EPA, success rate, CPOE, aDOT, target and air-yard share from the nflverse play-by-play over the same games; snap share from nflverse snap counts. EPA per dropback includes sacks and scrambles. Carries are the official ESPN rush attempts; EPA per designed run leaves out quarterback scrambles (they count as dropbacks) and kneel-downs, so for a quarterback the two counts differ. Per opportunity divides counting stats by nflverse dropbacks (passing), ESPN targets (receiving) and ESPN carries (rushing); other counts go per game. Percentiles rank each value among players at the same position with enough volume in the same period (the same groups as the player cards: QBs 12 dropbacks a week, RBs 4.5 carries, wide receivers 2.5 targets, tight ends 2, defenders half the games; fewer than 8 peers, no percentile). The bars compare the players on the page only, not the league.
