What happened: PFF evaluated non-championship seasons since 2006 using advanced grades and traditional statistics. The exercise weighs overall performance rather than playoff finish alone.
Why it matters: Both selections reached the championship game before their unbeaten or overtime runs ended. Their placements show how dominant two-way performance can survive a title-game loss in historical evaluations.
By the numbers: New England opened 18-0 and produced 0.249 EPA per play. Philadelphia earned a 93.7 overall grade, ranking second on offense and first on defense.
What to watch: The comparison serves as an offseason benchmark as both franchises prepare for the 2026 season.
