How football's opponent-adjusted efficiency metric works — and how to read a number that lives on a percentage scale.
Three efficiency metrics, one decision: what each measures, where they agree, and why they sometimes disagree.
How tracking data turns every throw into a probability — and isolates a quarterback's accuracy from scheme.

Opponent adjustment and the Simple Rating System, so you can compare teams on a level field.
One formula that rewards touchdowns, punishes interceptions, counts sacks — and predicts winning better than passer rating.
Raw rushing yards reward blocking and volume. How tracking data isolates what the back actually added.
Why pressure rate beats sack totals, what win rates measure, and the hard problem of dividing sack blame.
