What projects, and what doesn't · RBs · held out 2019-2025
How well one season predicts the next, measured on seasons the model never trained on. 1.00 would be perfectly predictable; 0.00 means last year told us nothing.
- Usage share (volume)0.52Beats guessing the RB average by 18%. n=4,219 RB seasons
- EPA per play (efficiency)0.10Not projectable — we do not forecast this. n=3,575 RB seasons
- Total EPA (value)0.41Beats guessing the RB average by 9%. n=3,575 RB seasons
Across all positions, usage carries year to year at 0.47 and efficiency at 0.07. So J'Koby Williams's projection is a projection of opportunity — how much of the offense he runs through. How well he converts it is something this model does not claim to know a year in advance, and the number above is why.

Air yards
Where the ball goes, and how much of the gain is the throw rather than the run after it.
The ball travels -1.8 yards in the air on an average target — 10.8 yards shorter than the median. Another 8.9 comes after the catch.
Where he is targeted
targets · completion rate · yardsDepth and direction come from CFBD’s passing detail, which is backfilled after the games: this covers weeks 1–2 only. Spikes, throwaways and intentional grounding are excluded before any average.

Historical Comparables · RB · efficiency + volume + value
Players from 2013–2025 matched on EPA efficiency, play volume, and adjusted value tier — not just one metric.
Comps are statistical — efficiency, volume, and value tier all factor in. Style and conference context differ.
