NFL Per-Snap Impact

The box score is opportunity-blind — a receiver with 900 yards on 850 snaps and one with 900 yards on 500 snaps look identical in totals, but the second is far more dangerous per opportunity. SIS measures production per snap, z-scored within position so a rotational pass-rusher is compared to an every-down star fairly.

How to read Snap Impact Score (SIS)

What the number means

  • 85-100 = elite per-snap impact; the player creates standout value whenever on the field.
  • 70-84 = high-impact starter or dangerous specialist.
  • 55-69 = above-average role efficiency.
  • 40-54 = roughly average impact; totals may still be strong if workload is massive.
  • Below 40 = limited efficiency, low usage, or weak statistical signal.

How it is built

  • Each position group's headline rate is normalized within position: EPA/snap for QBs, yards/touches per snap for skill players, disruption per 100 snaps for defenders, and workload-stability proxies for offensive linemen.
  • Rates are shrinkage-regularized, so tiny samples move toward the group mean instead of rewarding one-play spikes.
  • SIS is an efficiency score, not a total-value stat. Pair it with snap share: high SIS + high snaps is an every-down star; high SIS + low snaps is a specialist or role-expansion candidate.

Compare within position first. A 78 edge rusher and a 78 receiver both stand out, but their inputs are position-specific.

Reliability is sample context. Elite/Consistent/Reliable/Volatile/Emerging describes how stable the sample is, not just how good the player is.

Coverage: Snap counts begin in 2012; players whose careers predate the snap era do not receive a Snap Impact Score. 3,454 players cleared the 500-snap floor.

Workload vs. Efficiency Quadrant

Each dot is a player. The four zones reveal archetypes invisible to ranked lists: elite all-rounders land in the top-right; rotational specialists in the top-left; volume players in the bottom-right; depth players in the bottom-left.
