Running back

The relationship is about as tight as anything in fantasy football, which is the first thing worth saying: points follow high-value touches, so the argument about a back is really an argument about how many he will get. McCaffrey sits alone at 9.8 per game, nearly three times the league median of 3.7.

The useful names are the ones off the line. A back sitting below it is being given the work and not converting it, which is usually offense quality rather than the back. Above it, he is scoring on less, which is efficiency that regresses. Neither is a buy on its own; both are a question worth asking before you spend a second-round pick.

Yards before contact is the offensive line’s point-of-attack blocking. Yards after contact is the back. Splitting them stops you crediting a runner for his line, or blaming him for it, and the pairs inside one backfield are where it gets useful.

Gibbs and Montgomery run behind the same line and post the same yards after contact; Gibbs simply gets more space, because Montgomery is the one taking the heavy boxes and the short yardage. Walker and Charbonnet is the same story with the roles reversed. When two backs share a line, the difference in yards before contact is a difference in role, not ability, and role is the thing that changes in September.

Route participation says a back is out there on passing downs. Targets per route run says the quarterback is looking at him. The bottom-right corner is the trap: high participation, no targets, which is a back running routes as a decoy, whose receiving usage looks real in a box score and produces nothing.

McCaffrey and Gibbs clear the field on both axes, which is why they price the way they do. Further down, the Seattle backfield draws few targets either way, which reads as system preference rather than a depth chart to bet on.

Twenty-seven finishes, and no single profile among them. Henry’s 2020 is 378 carries and 31 targets; McCaffrey’s 2019 is 287 and 142. Both finished top three, and nothing about the first tells you how to value the second. Read down a column rather than across a row: the median is the bar, and the spread around it is how much the bar moves.

The two rank columns are the ones people skip. The median top-three back ran behind the 12th offensive line on the 12th ranked offense: not an elite situation, but not a bad one either, and the 75th percentile at 20th says a genuinely poor line has produced this finish more than once. Age is the tighter constraint: 22 to 26 covers the middle half, and only two seasons in nine years came from outside it.

Every team’s most-used back, by his share of the carries and targets that went to the backfield. The spread is the story: 84% at the top against 33% at the bottom. The top of this table is where bell-cow backs live, and there are far fewer of them than there are picks in the first two rounds.

Read the bottom half as a warning rather than a ranking. A back at forty percent of his own backfield is one injury or one hot hand from being a committee piece, and no amount of talent in the abstract fixes a snap count.

Carries depend on the scoreboard. Targets mostly do not. A back who catches passes keeps scoring in the games his team is losing, which is exactly when a rushing workload disappears. That is why Christian McCaffrey at 129 targets has a floor that a pure runner on the same volume does not.

Compare this order against the one above it. A back near the top of both owns his backfield in every game state. A back high on opportunity share but low here is a game-script bet, and worth less in a league that starts a flex.
