The read

Nohl's best number is passer rating allowed: 71, 21st of 96 among cornerbacks.

Written from his numbers, not from film. 4 games are behind the season figures.

How he stacks up

Every graded stat at a glance, against all the cornerbacks in the league.

Left is the worst at his job, right is the best, and the line down the middle is average. The bubble is his percentile: 90 means better than nine in ten qualifying cornerbacks. Faded bars are still small samples.

How he has progressed

Where he has ranked among cornerbacks after each week, and every game behind it.

WorstMiddleBestrecent12345Week 2: 80th percentileWeek 3: 30th percentileWeek 4: 70th percentile70th

Season rank slipped: 80th to 70th percentile since Wk 2.

The line is his season-to-date rank among players at his position after each week, from 100 (the best) to 0 (the worst). It rises when he passes other players, not when he has one big game. Early weeks are noisier because fewer plays are behind them. The shaded weeks are the recent stretch.

Lower is better for this stat. One game is a small sample: a single stat over 4 targets can swing on a handful of plays. Shaded rows are the recent stretch.

The numbers, in context

Each one against every cornerback with at least 10 targets. Right on the strip is better.

Yards allowed per target

Above typical

6.3lower is better

30th of 96 cornerbacks · top 32%

The yards the receiver he is covering gets each time he is targeted. Fewer is better.

The box score: Interceptions are rare and say little about the hundred plays where he is just covering.

Does it show up in winning? Across 143 games league-wide, teams won 72% of the time when their cornerback was in the best third on yards allowed per target, and 55% when he was in the worst third.

Passer rating allowed

The passer rating of quarterbacks throwing at him. 158.3 is perfect for the passer, so lower is better for the defender.

Does it show up in winning? Across 143 games league-wide, a good or bad game on completion rate allowed from a cornerback has not lined up much with his team winning (64% wins in the best third, 53% in the worst).

How often a pass thrown at him ends with him breaking it up. A cornerback does this far more often than he intercepts.

The box score: Passes defended are counted, but never against how often he was tested.

How he plays

Tendencies: how his game differs from the cornerbacks around him. These are not better or worse, only different, and often say as much about the offense or defense he plays in as about him.

Depth of passes at him

Style

10.6 yds

Right around the middle of cornerbacks: a typical one is 10.6 yds.

How far downfield the passes thrown at him travel on average. It shows whether he is tested deep or underneath, which is a role, not a grade.

Small sample: could move a lot · 17 targets

Playing time

He has played in 4 of his team's 4 games with snap counts, on the field for about 94% of the team's defensive plays when he plays.

Each column is a game: the share of his team's defensive snaps he played. 80% means about 8 of every 10 plays. “Out” means he did not play; a question mark means snap counts are not posted yet. Shaded games are the recent stretch.

Game by game

Every game this season: how it ended for his team, how much he played, his box score, and the advanced numbers from that one game. One game is a small sample, so read the right-hand columns as a snapshot, not his level.

Players with a similar profile

The cornerbacks whose grades are closest to his across the same stats. Similar means similar numbers, not the same style of play.

Ranks are among players at the same job who have enough plays to be graded. Grades and rankings come from play-by-play, charting and snap-count data, so they cannot see blocking, route running or assignments. See how the grades work.
