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 Mekhi Nelson'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.

Third-down weapon out of the backfield. Routes, hands, and separation in coverage define this role as much as rushing.
- ▸Below-average efficiency vs RB peers — value comes through volume, not per-play impact.
- ▸Limited usage share suggests a rotational or specialist role.
- ▸High game-to-game variance — boom-or-bust profile.
- ▸Production faded as the season progressed — 0.11 EPA/play decline from first to second half.
- ▸Peak game: 0.93 EPA/play in Wk 6 vs Michigan State (SP+ -3).
