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.
The address bar is the share link. Copy it, text it, post it: whoever opens it sees the same players. The Compare button on player pages builds on this set until you start over or switch positions.
Each bar is the league pool; the markers are the players. Right is better, the dashed line is the median. The best value in each row is marked green.
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.
Justin Herbert
Brock Purdy
Green cells turn targets into points, red cells lose them. Cells with one target are left grey.
Brock Purdy gets the most from the ball in the air (+80.8 EPA), Justin Herbert gets the most scrambling (+29.0 EPA), and Justin also gives the most back on sacks (−84.4).

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.

Back to back by depth band. The widest band is where the offense goes to him; the gap between solid and faded is where it misses.

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.
Thresholds are the quartiles of every game week by qualified quarterbacks this season (598 player weeks). The right column is the average week and its swing.

Ranks are among players at each one's own position. A missing bar is a week he did not score: a bye or a missed game. The format you pick is remembered on this device.
