How this is estimated

Experimental DT projection: qualified current-season grades from the previous four weeks, weighted by snaps and recency and regressed toward 50. Opponent unit pass and run performance adjusts the estimate by at most four points. Limited game history; low confidence.

Weekly CFI is a same-position percentile grade using the published weekly play and production fields. CFI uses the same position model as the leaderboard. A dash means the source data or a qualified model is unavailable. Historical production is from nflverse; charted blocking and pressure metrics cover published charting reports only. Missing values are left blank rather than estimated.
