Every season a few teams finish near the top of the league in penalties and a few finish near the bottom, and the gap between them is not small. Fans of the flagged teams have an explanation ready by October. The league has a different one. Both can point at the same table.
Three things produce a high penalty count. Only one of them is officiating.
Explanation one: the team is undisciplined
The simplest reading, and the one coaches accept in public. Pre-snap fouls are the cleanest evidence for it. A false start is not a judgment call. Nobody debates whether the tackle moved.
This is why the discretionary and non-discretionary split matters so much. Public analytics work on play by play data has found that most team penalty rates bounce around year to year and predict future results poorly, with one exception: the least discretionary fouls. False starts and defensive offside carry real signal about discipline. Most defensive judgment penalties behave closer to noise.
So if you want to argue a team is sloppy, argue it with false starts. That is the column where the claim survives contact.
Explanation two: the scheme buys the flags on purpose
A defense that plays aggressive press coverage will draw more defensive holding and more illegal contact than a defense that plays off. That is not indiscipline. That is a coordinator deciding that the coverage is worth the occasional five yards.
The same logic runs through the offensive line. A pass heavy team gives its tackles more snaps in space against edge rushers, which is where holding comes from. Run more, drop back less, and the holding number falls without anybody getting more disciplined.
Penalty totals are partly a readout of style. Two teams can commit fouls at identical rates per opportunity and finish the season fifteen spots apart because one of them had far more opportunities.
Explanation three: the team is officiated differently
The hardest one to establish, and the one everybody reaches for first.
It is not absurd on its face. The strongest experimental evidence in any sport comes from soccer, where Nevill and colleagues showed qualified referees video of identical challenges with and without crowd noise, and with the noise on they called fewer fouls against the home side. Officials are human decision makers under pressure, and pressure has a measurable direction.
The football version points somewhere less satisfying. An analysis of NFL penalties in games with and without crowds, published in the Journal of Sports Economics, found the clearest crowd effect on defensive penalties tied to snap count communication rather than on judgment calls. Noise made the cadence harder to hear. That is a real home advantage and it is not a thumb on the scale.
For a claim about your specific team you need more than a season total. You need the rate per opportunity, the same rate for comparable teams, and some accounting for who they played and where.
How to tell the three apart
| If you see | It points at | Because |
|---|---|---|
| High false starts and offside | Discipline | These are the least discretionary fouls in the book and the most stable year to year |
| High defensive holding and illegal contact, low elsewhere | Scheme | Press coverage buys these deliberately; the trade is coverage for five yards |
| High offensive holding on a pass heavy team | Opportunity | More dropbacks means more snaps where holding is available to call |
| A gap that survives per-snap adjustment and opponent adjustment | Worth investigating | Most apparent gaps do not survive either one |
| A gap that only appears in games your team lost | Your memory | Calls against you get stored; calls for you get thrown out |
The part nobody wants
In 1954 Hastorf and Cantril showed Dartmouth and Princeton students film of the same brutal game between the two schools and asked them to record infractions. Princeton students recorded roughly twice as many Dartmouth violations as Dartmouth students did. Same film. Same plays.
The mechanism is not lying. It is what gets stored. A flag against your team lands as an event. A flag in your favor lands as normal football and disappears by Tuesday. By Wednesday your memory is a highlight reel of injustice with the counterexamples deleted, and it feels like recall because it is recall. It is recall of a biased sample.
That is most of the distance between what the table says and what the group chat says.
What to do with it this season
Track your team’s flags in both directions in the same place. Log the ones that went your way with the same care as the ones that did not. That single habit does more than any statistic to fix the sample your opinion is built on.
Then count leverage rather than volume. Nine low leverage flags are a nuisance. Two high leverage ones are the game, and win probability added is how you tell them apart. Before you blame the crew for the number, check what a crew report actually has to show you.
