NFL playbook

How the NFL market behaves, and what to check first · 8 min read

The NFL is the most bet and most studied market in American sports. That makes it the hardest to beat: its edges are small and easy to give back through a bad price. This playbook is the NFL layer on top of Levels 1 to 3.

How the NFL market works

The NFL runs on a weekly cycle. Next week's openers go up on Sunday night, soon after that day's games end, and some books hang look-ahead lines a week earlier still. Early limits are low while the sharpest bettors correct the number. Through the week news arrives, the number settles and limits rise, reaching their highest close to kickoff (see What happens to a line until kickoff). Three things follow:

• The close is very hard to beat. With a huge handle and every serious modeler watching, the NFL closing line is among the most accurate prices in sports. A real edge on an NFL side is a couple of percentage points, not ten. If a number promises far more, suspect the number first.
• Timing matters. Value is mostly found early in the week or right after news breaks. Why lines move and Steam and market makers show how to tell information from noise.
• The sample is small. Each team plays fewer than 20 regular-season games, so a season of NFL bets says little on its own. Judge yourself on closing line value, not on a month of results.

Spreads and key numbers in practice

NFL scoring comes in field goals and touchdowns, so final margins cluster. Historically, about 1 in 7 games ends with a 3-point margin and about 1 in 11 with a 7-point one; 6 and 10 come next. Key numbers does the math. In practice:

• A hook across 3 or 7 is expensive for a reason. −2.5 and −3.5 are very different bets, and so are −7 and −7.5. Across 8 or 9, a half-point is worth a sliver. Value every hook by the games it wins or loses you.
• Read the price with the number. Books hate moving off 3, so they move the price first: −3 at −110, then −115, then −120, before the number finally crosses. Laying −3 at −120 can still beat laying −3.5 at even money, because so many games land on 3.
• Buying points. Buying onto or off 3, and sometimes 7, can be worth the extra price; buying through 5 or 9 rarely is. Books often charge more around 3 and 7, so do the arithmetic.
• Teasers. A teaser moves each spread on the ticket your way, usually by 6 points, but pays like a parlay: every leg must win and the hold compounds (Parlays and correlation). Most teasers are bad bets. The best-known case, the Wong teaser, named for the author who popularized it, uses the 6 points only where they cross both 3 and 7: underdogs of +1.5 to +2.5 teased up to +7.5 to +8.5, and favorites of −7.5 to −8.5 teased down to −1.5 to −2.5. At a typical two-team price of −120, each leg must win about 74% of the time just to break even. In games since 2015 the favorite legs have won less often than that and the underdog legs only about that often, and many books now charge more. Teasing across no key numbers rarely earns back the hold.

Moneyline or spread?

The spread and the moneyline are two prices on the same game. What separates them is the games where the favorite wins without covering: those win a moneyline bet on the favorite and lose, or push, a spread bet. For a 2.5-point favorite that slice is only wins by 1 or 2, so the two bets are close substitutes and the better price usually decides it. For a 7-point favorite the slice is every win by 1 to 6, which is why its moneyline costs so much more. Historical results map them roughly like this:

The underdog's fair price is the mirror image, and books add vig to both. Use the map as a sanity check: if a book's moneyline sits well away from where its own spread implies, one of the two is the better bet.

Over/unders

An NFL over/under is a bet on pace, efficiency and the quarterbacks. What moves it:

• Pace and play-calling. Fast, up-tempo teams create more plays for both sides; slow, run-first teams and a team protecting a lead shrink the game.
• Wind, above all. Strong, steady wind hurts passing and kicking, and it moves scoring more than any other weather. Cold and rain matter less than most bettors assume. Domes and closed roofs take weather out entirely, so check the roof.
• Forecasts change. The market moves on forecasts quickly, so the edge is in reading them well and early, and the risk is that they change.
• Key numbers are weaker here. Combined scores cluster less than margins do. Common landing points like 37, 41, 43 and 44 each happen only a few percent of the time, nowhere near the 1 in 7 a 3-point margin gets, so a half-point across one is worth something, but far less than a hook across 3.

Information that moves NFL lines

The market prices most news fast. Roughly in order of size:

• The quarterback. No other position comes close (QB impact). A starter ruled out can move a spread by anything from a point or two to around a touchdown for the very best, depending on how much worse the backup is.
• The injury report through the week. For a Sunday game, practice reports come Wednesday, Thursday and Friday; on a short week they come earlier and are often estimates. Missing early practices and returning by Friday differs from never practicing. Game statuses arrive at the end of the week, and the final inactives list shortly before kickoff. Most non-quarterback absences matter less than the headlines suggest, but several missing starters in one unit, like the offensive line or the secondary, add up fast (injury impact).
• Rest and travel. Short weeks, byes, long trips and rest differences are real but small, well known and already in the price. A team off a bye is not a bet by itself.
• Divisional games. The old idea that they play closer than their spreads has thin evidence and is priced in: a tiebreaker at most.

The common thread: if you heard it on a pregame show, the market heard it first. An edge from news comes from being early or judging it better, not from knowing it.

Props and same-game parlays

Player props, like passing yards or receptions, are less efficient than sides and can be slow to react to news, but they carry more vig and lower limits. NFL same-game parlays are a book favorite for a reason: legs from one game are correlated, the book prices that in, and it holds far more than on a single bet. A quarterback's yards, his top receiver's yards and the over all ride the same game script. Read the parlays lesson before you build one, and stake any parlay smaller than a single bet.

A pre-bet checklist

1. Is the quarterback confirmed? If either starter is in doubt, know how far the line has already moved for it.
2. Which side of 3 or 7 are you on? Weigh the half-point against the price.
3. Have you shopped the price? Compare books first (Line shopping).
4. What has the line done since it opened, and why? News or respected money? If the price you wanted is gone, the new one needs its own check.
5. Outdoors? Check the wind, and whether the roof is open.
6. Moneyline or spread? For small favorites and small underdogs, compare both prices for the same opinion.
7. Parlay or teaser? Does every leg earn its place, and is anything left after the hold?
8. Is the stake small? One shared misread can sink several of a Sunday's bets, so size for a bad day (Variance and drawdowns).

How Consensus Edge helps

We compare prices across many sportsbooks and remove the vig, so you can see what the market really thinks and where the best price is. We blend Square (the books), Sharp (our models) and Crowd (prediction markets) into one chance, and we re-price regularly until kickoff, so injury news and line moves reach our numbers. Each bet shows BET, LEAN or NO EDGE; BET and LEAN carry a small suggested stake, and we publish how our picks did against the close. NO EDGE is common and honest: a fair price, or a market we don't grade. Start on the slate or read how it works, and bet only what you can afford to lose.
