NFL Aging Curves

When does each position peak, and how fast does it fall off? Every player's per-snap production is scaled to his own best season, so the curve measures aging as a shape — not which stars happened to be young. Snap-count era, 2012+.

Peak Age by Position

PositionPeak ageDrop by +5 yrsSample
Defensive Backs2110.6 (by 26)2,775
Running Backs2110.2 (by 26)1,028

Drop = points of peak-relative index lost five years after the peak age (100 = a player's own best season).

each player's seasons are scaled to their own peak (=100); a position-age point needs ≥20 player-seasons. Coverage 2012+ (snap era, incl. 2025).

Aging is measured as a shape, not a level — great players and journeymen each contribute their own curve.
