Breece Hall out-gained Josh Jacobs by 204 yards on identical catches — yet finished 8 fantasy spots back, on 9 fewer TDs

You draft off a running back's fantasy finish. We read the whole 2025 regular season — all 46,452 offensive plays in the nflverse play-by-play file, weeks 1 through 18 — and rebuilt every carry and target for every back, then scored them in full-point-PPR (1 point per reception, 0.1 per rushing or receiving yard, 6 per touchdown, minus 2 per fumble lost). Of the 149 running backs who touched the ball, 55 cleared 100 opportunities (carries plus targets); that is the pool below. Take two of them. Breece Hall of the New York Jets: 243 carries for 1,065 yards, 36 catches on 48 targets for 350 yards, 5 total touchdowns, 2 fumbles lost — 291 opportunities, 14th-most in the pool, 203.5 PPR points, which finished RB21. Josh Jacobs of the Green Bay Packers: 234 carries for 929 yards, 36 catches on 44 targets for 282 yards, 14 total touchdowns, 2 fumbles lost — 278 opportunities, 17th-most, 237.1 points, RB13. Hall out-gained Jacobs by 204 yards from scrimmage (1,415 to 1,211), caught the identical 36 passes, and lost the ball the same two times. On every fantasy point that was not a touchdown, Hall outscored Jacobs 173.5 to 153.1. Then the touchdowns land: Jacobs reached the end zone 14 times to Hall's 5, worth 84 points to 30, and the finish inverts — Jacobs RB13, Hall RB21, eight places apart. Both figures are corroborated at ESPN, whose 2025 game logs list Hall at 243-1,065-4 rushing and 36-350-1 receiving, Jacobs at 234-929-13 and 36-282-1. Across the full 55-back pool, opportunity and fantasy points correlate at 0.94 (Pearson), and 418 of their 12,285 carries and targets — 3.4% — produced a touchdown.

The following is analysis, not fact. The single-team manager sees two numbers: RB13 and RB21. From the whole-pool vantage those two backs are separated at the finish overwhelmingly by one input. Rank the 55 by opportunity and rank them by PPR points and the two orders agree at 0.94 (Spearman) — volume is very nearly the whole story of a fantasy finish. What the correlation does not absorb is a residual that touchdowns dominate. Of the 24 backs who finished RB24-or-better in points, 21 also sat in the top 24 by opportunity; only three climbed into the scoring top 24 from outside it (Kenneth Gainwell, RJ Harvey, Zach Charbonnet), and exactly three did the reverse — top-24 workloads that scored outside the top 24 (Quinshon Judkins, Tyrone Tracy Jr., Woody Marks). Touchdowns are the largest mover in each of those six swaps. Hold the touchdowns constant and the pool barely reorders; let them float and you get Hall and Jacobs. The tell is how unevenly that rarest input is spread. Among those same top-24 backs, the share of fantasy points that came from touchdowns runs from 14.7% (Hall) to 40.1% (Charbonnet) — a 2.7-fold range, on the one event that happened on 3.4% of touches — with a median of 25.5%. Jonathan Taylor finished RB4 on 380 opportunities, and a third of his points (33.1%) were his league-leading 20 touchdowns. Saquon Barkley collected the 7th-most opportunities in football and finished RB14, because 9 touchdowns is a modest yield on 332 touches. Two RB1-tier and RB2-tier seasons can rest on opposite proportions of the least frequent thing a back does, and the box score that a manager reads prints only the sum. Touchdown rate per touch is the rarest of a back's inputs — 3.4% of touches in this pool — and the most unevenly spread across it, which is why the decomposition is worth doing at all — a statement about how 2025's points were composed, not a forecast for any one player.

Touchdowns are not pure noise, and the honest counter is that some of this spread is role, not luck ^mmodeled. A back who gets the goal-line carries — short-yardage specialists, the lead back in a run-heavy or high-scoring offense — will convert opportunities into touchdowns at a durably higher rate than a between-the-20s early-down back, and that edge can repeat because the usage repeats ^mmodeled. Jacobs' 14 scores are partly Green Bay handing him the ball inside the 5; Hall's 5 are partly a Jets offense that reached the goal line less often and split the work when it did ^sspeculative — the free play-by-play carries the touches but not the coaching intent behind them. So "the gap is touchdowns" is a decomposition, not a verdict on which back is better or what either does next; a reader who believes red-zone role is sticky will read Jacobs' share as earned, and a reader who treats touchdown rate as mostly variance will read Hall's yardage as the steadier signal — the data supports stating the split, not resolving it. Two limits bound even the arithmetic: full-PPR scoring flatters the pass-catching backs (a half-point or standard league reorders the margins, though not the direction of the Hall-Jacobs inversion, which is 204 yards and 9 touchdowns in any format), and this is one regular season — 55 backs, weeks 1 through 18 — not a multi-year base rate.
