Christian McCaffrey or James Cook III?
Christian McCaffrey or James Cook III? Both are RBs. Here is what each man's 2025 season was actually built on, updated Aug 1, 2026. Christian McCaffrey leads on share of his team's offensive snaps and rushing attempts, and also on receiving expected points added — one side of that is opportunity, the other is efficiency, and they have not historically travelled together. James Cook III's edge sits in rushing yards over expected and rushing yards over expected per attempt — efficiency rather than opportunity, and the file measures that as the less repeatable half. Figures are 2025 verified play-by-play (nflverse); scored Half-PPR. Repeatability is measured from year-over-year persistence across 2016 to 2025, not projected. Muffed publishes no projections, draft grades or start/sit advice.

“Repeats” is measured year-over-year persistence across 2016 to 2025 — opportunity carries between seasons, scoring rate largely does not. This describes what a 2025 season was built on. It is not a forecast, and Muffed publishes no projections, draft grades or start/sit advice. How we measure it.
