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 Lamar Sperling'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.
