Defense rankings — 2026 Week 16
Use this for the order, not the number. Ranking defenses this way is about twice as good as ranking them by season-to-date fantasy points (Spearman 0.29 out of sample vs 0.13) — but half of what a defense scores is turnovers and touchdowns, which nothing predicts.
No posted line for any game this week yet, so there is
nothing to project. Rankings appear once the lines are up.
Projected points allowed comes from the posted total and the opponent's implied
total; the tier column is the expectation across the points-allowed tiers, not the
tier a single projection happens to land in. Defensive touchdowns and safeties are
the league mean — nothing forecasts them
(fitted 2019-2025).
Measured walk-forward, one season held out at a time: Spearman
0.295, MAE 4.27 against a
4.41 league-mean baseline, R² 0.079
over 3,136 defense-games. The R² is the honest ceiling: this
orders defenses, it does not predict their scores. Study at
