The read
Byron grades about average among cornerbacks so far, with no number far from the middle.
Lately he is playing worse. Passes defended per target is 0% over the last 2 games (8 targets), against 17% before that. A few plays could easily explain this. Worth watching, not worth believing yet.
Written from his numbers, not from film. 5 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.
Season rank slipped: 35th to 23rd percentile since Wk 1.
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 7 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
▼Well below typical
8.9lower is better
73rd of 96 cornerbacks · bottom 25%
11.2worse to better4.2
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.

82lower is better
36th of 96 cornerbacks · top 38%
115worse to better62

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
9.3 yds
Right around the middle of cornerbacks: a typical one is 10.6 yds.
5.4 ydslow to high14.2 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.
Playing time
He has played in 4 of his team's 4 games with snap counts, on the field for about 95% 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.

The box score
The traditional totals, with where each ranks among cornerbacks. A total rewards volume, which is why the advanced numbers above matter.
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.
Data: nflverse play-by-play, CC BY 4.0. Also FTN charting, Pro Football Reference advanced stats, snap counts and injury reports, all through nflverse. Calculations and charts by Raiders Rundown.
