The NFL Trends That Separate Real Contenders From September Mirages

Chicago football fans know the September illusion better than most. A team starts hot, the talk shows start drawing up playoff scenarios, and by Thanksgiving the whole thing has come apart. After a breakthrough 2025 season under Ben Johnson, the 2026 Bears are carrying real expectations, which makes this a good moment to ask which early signals actually mean something. The answer is a handful of well-established trends that separate genuine contenders from mirages, and they show up early for anyone willing to look past the win-loss column.

The Record Lies, and Chicago Has the Receipts

The win-loss record is one of the least reliable indicators of a team’s true quality in the opening weeks. It decides seeding, so it feels like the number that matters, but as a predictor of what comes next it is badly flawed. The problem is sample size. A seventeen-game season is short, and the first month produces only a few data points, each shaped by injuries, turnovers and bounces that will not repeat.

The 2024 Bears are the local cautionary tale. They opened 4-2, including lopsided wins over Jacksonville and Carolina, and the city started talking about the NFC North race. Then came a ten-game losing streak, a midseason coaching change and a 5-12 finish. The early record told Chicago one story. The weeks that followed told a very different one.

The Close-Game Trap

The most seductive version of the trap is the close-game record, because it fools fans in both directions. A team that goes 5-1 with five one-score wins looks like a contender, yet winning tight games at a high rate is one of the least repeatable feats in football. Those games turn on a tipped pass, a blocked kick or a clock decision in the final thirty seconds, and that kind of luck does not hold for long.

This is where the NFL Betting Odds become genuinely illuminating, because the market is far less impressed by a gaudy record built on narrow escapes than a packed sports bar in Wrigleyville tends to be. A team riding a string of one-score victories will often be priced as an underdog against opponents it appears, on paper, to be outperforming, because sharper analysis strips out the unsustainable close-game success and prices in the regression still to come.

Chicago has lived the other side of that coin too. When the Bears fired Matt Eberflus in November 2024, WLS-TV laid it out: he left with a 5-19 record in one-score games, the worst mark in NFL history for a coach with at least 20 of them. The same report noted that in 2023 the Bears lost three games after leading by ten or more in the fourth quarter, tied for the most in a season in league history.

Point Differential Is the Tell

If the record is unreliable, point differential is the better guide. How much a team outscores its opponents predicts future wins far better than the record does, because it carries more information. A record is a list of binary outcomes. Point differential captures the margin of every game, which turns each Sunday into a richer measurement of how a team actually played.

The franchise’s greatest season shows what the real thing looks like. The 1985 Bears finished 15-1, scoring 456 points and allowing just 198, a margin of 258. A game-by-game results page tallies it clearly: only three of those fifteen wins came by a single score, and several were routs, including 44-0 in Dallas and 36-0 against Atlanta. That is what a hot start backed by substance looks like. When a September run is built on blowouts, it tends to last. When it is built on escapes, it usually evaporates.

Regression to the Mean Is Not an Opinion

Underneath all of this sits a principle that is not up for debate: regression to the mean. Extreme performances, good or bad, drift back toward the average over time. A team playing far above its true level will come back to earth, and a team playing below it will tend to climb. That is not pessimism. It is arithmetic, and it works on every roster whether anyone in the building believes in it or not.

Chicago is a market where early-season verdicts get argued loudly, on talk radio, in message boards and at every bar stool near Soldier Field. The voices worth trusting in those arguments, whether a Chicago host or a regional commentator like garrett bush ohio university football fans might recognize from the airwaves, tend to frame September results with healthy skepticism rather than crowning a darling after three weeks.

What Real Contenders Actually Look Like

Put these trends together and the profile of a genuine contender becomes clear. It wins by comfortable margins, carries a strong point differential, does not lean on an unsustainable close-game record, and posts efficiency numbers that support its results. A mirage does the opposite. It survives tight games, wins without dominating, and rides a record its point differential cannot justify.

Cubs and White Sox fans hear the same argument every summer in the form of run differential, and it holds across sports for the same reason. By the quarter mark of an NFL season, the margin is already speaking, the close-game record is already flashing warnings or reassurance, and the gap between a team’s record and its underlying play is already measurable.

What Soldier Field Can Tell You by Week 4

The current Bears are a live test. Through three weeks they are 2-1, with a 59-37 shootout win over Carolina, a 9-3 home loss to Minnesota, and a Monday night upset of the unbeaten Eagles as four-point home underdogs with Case Keenum starting at quarterback. Coverage of that win argued the defense has found an identity, and the margins over the next few weeks will say more about whether that holds than the record will.

Early excitement is part of being a Chicago fan, and nobody should talk themselves out of enjoying a hot start. The trends that actually predict how a season unfolds are less fun: watch the point differential, distrust a pile of one-score wins, respect regression, and treat the standings as the least reliable number on the page until well into October.

Do that, and the difference between a real contender and a September mirage stops being a lesson learned painfully around Thanksgiving. It becomes something visible from the stands by Week 4, long before the rest of the city catches up.
