Compare players

Two or three players of the same position, side by side: where each one grades against the league, where the ball finds each of them, and how their weeks line up.

Every trait is a share of his own dropbacks, so volume does not move it. Each bar is the league's qualifying quarterbacks; the markers are the players and the thin line is the median. Styles are not grades: a high or low share describes the role, not how well he plays it. The tags are each player's traits furthest from the middle.

Every play is split by what happened: completions at the catch into air yards and yards after the catch (nflverse's air EPA), the cost of the ones that fell incomplete or were picked, sacks, scrambles and designed runs. Bars share one scale, gains right of the line and losses left. The rate is per dropback, with its percentile among the league's qualifying quarterbacks; the best rate in each row is green.

Each line is a player's trailing 3 games (rates are pooled over the games, not averaged); the faint dots are single games. The shaded band is the league's middle half of single games at the position, the dashed line its median. A line that climbs out of the band is a role getting bigger.
