What projects, and what doesn't · QBs · 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)0.46Beats guessing the QB average by 16%. n=2,421 QB seasons
- EPA per play (efficiency)0.05Not projectable — we do not forecast this. n=1,965 QB seasons
- Total EPA (value)0.51Beats guessing the QB average by 20%. n=1,965 QB seasons
Across all positions, usage carries year to year at 0.47 and efficiency at 0.07. So Luke Duncan'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.

Elevates on passing downs — 3rd-and-medium, two-minute drills, and pressure situations are where this QB is best.
- ▸Below-average efficiency vs QB peers — value comes through volume, not per-play impact.
- ▸High-volume role — one of the team's most-used QBs by play share.
- ▸Particularly dangerous on passing downs — efficiency spikes in obvious pass situations.
- ▸Peak game: 0.42 EPA/play in Wk 13 vs Washington (SP+ 18).
