Do NFL teams run more when they're winning?
Yes in games that actually finish lopsided, no in any way you can predict beforehand. Pass rate barely moves by projected spread (57.3%-57.9%) — but games that finish 14+ points apart average 41.2 competitive snaps per team, against 58.5 in close games. The real effect is fewer opportunities for everyone, not different play-calling.

The evidence
Two different cuts of the same question — predictable-beforehand (by projected spread) versus realized-after-the-fact (by actual final margin)
| Cut | Competitive snaps/team | Pass rate | Team-games |
|---|---|---|---|
| Spread under 3 (predictable) | 53.9 | 57.7% | 748 |
| Spread 3-6 | 53.8 | 57.9% | 1204 |
| Spread 6-10 | 51.6 | 57.3% | 770 |
| Spread 10+ | 47.7 | 57.8% | 368 |
| Final margin under 14 (realized) | 58.5 | 57.8% | 2036 |
| Final margin 14+ (realized) | 41.2 | 57.6% | 1054 |
How this was measured
Computed from weekly team data with garbage-time snaps already excluded: team_epa_weekly's off_plays and off_pass_rate are both filtered upstream to plays with win probability between 5% and 95%, i.e. before a game's outcome is effectively decided — "competitive snaps," not a raw play count. Joined to game_schedule's spread_line for the predictable-beforehand cut, and separately to team_game_results' actual margin for the realized-after-the-fact cut, each team-week bucketed by the absolute value of its own number. 3,090 team-weeks total. The separate finding that adjusting a player PROJECTION for game script moved mean absolute error by only 0.02-0.04 yards (worse, not better, for passing/rushing) is a prior measurement across 8,172 individual player projections — a different comparison than the team-level numbers above, not re-derived from this app's own tables.
Sample size: 3,090 team-weeks. Last verified 2026-09-27.
What this doesn't tell you
This doesn't mean the spread is useless for play-calling intuition — it means the line alone isn't a reliable predictor of it, not that realized blowouts don't change the game. It also doesn't say which specific players lose the most opportunity in a blowout, only that the loss is real and roughly symmetric between the two teams.
This is a place to look, not a bet to make — every figure here describes the past, not a specific upcoming game.
