The read
Blake grades about average among running backs so far, with no number far from the middle.
Lately he is playing worse. Success rate is 18% over the last 2 games (11 carries), against 59% before that. The change points one way, but a few plays could still explain it.
Written from his numbers, not from film. 4 games are behind the season figures.
How he stacks up

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 running backs. Faded bars are still small samples.
How he has progressed
Where he has ranked among running backs after each week, and every game behind it.
Season rank slipped: 93rd to 74th 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.

The numbers, in context
Each one against every running back with at least 20 carries. Right on the strip is better.
EPA per carry

Expected points added: how many points the play added to (or took from) the offense's scoring chances, given the down, the distance and the field position. A 4-yard run on 3rd-and-8 loses points even though it gains yards.
The box score: Yards per carry credits a 5-yard run on 3rd-and-15 and ignores the goal-line carry that scores.
Does it show up in winning? Across 153 games league-wide, teams won 60% of the time when their running back was in the best third on EPA per carry, and 46% when he was in the worst third.

How he plays
Tendencies: how his game differs from the running backs 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.
Yards before contact
Style
3.5 yds
Gets big lanes, and more so than almost any of the running backs. A typical one is 2.3 yds.
1.6 ydslow to high3.0 yds
Yards per carry before a defender touches him. That is mostly the line and the scheme, so it is shown, not graded.
Runs to the edge
Style
32%
Gets to the edge, more than most running backs. A typical one is 25%.
14%low to high41%
The share of his carries run around the end instead of between the tackles.
Carries from shotgun
Style
12%
Runs from under center, and more so than almost any of the running backs. A typical one is 34%.
16%low to high49%
The share of his carries that start with the quarterback in shotgun, a sign of what kind of run game he lives in.
Playing time
He has played in 4 of his team's 4 games with snap counts, on the field for about 28% of the team's offensive plays when he plays.

Each column is a game: the share of his team's offensive 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 running backs. 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.
