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 KJ Jefferson'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.
