NFL Over/Under Betting Guide

What the Total Is

The total, or over/under, is both teams' points added together. The book posts a number and you decide whether the game goes above it or below. Who wins does not matter.

As with the spread, both sides are usually priced at -110, so you need to hit 52.4% just to stay even.

Wind, Which Almost Nobody Checks

Of all the weather, wind is the one thing that moves a total consistently. Rain and cold mess up a game less than people assume; teams are built to play wet.

Strong wind is different. It wrecks the deep passing game, makes long field goals a gamble, and pushes coaches toward running the ball — which also burns clock and cuts the number of possessions. That double effect, less efficiency and fewer plays, is what drags scores down.

Watch for domes and retractable roofs: weather is out of the equation there, and anyone betting the under "because of the weather" is betting on nothing.

What Actually Moves the Number

• The quarterback. A backup does not lower the total just by scoring less: he changes the game plan to something more conservative, and that drags both offenses down.
• Pace. Two fast-playing teams stack up possessions. Two that run and drain the clock take them away. Pace matters as much as quality.
• Injured defensive backs. A secondary missing its best cover men raises totals more than a banged-up offensive line does.
• Game context. A team eliminated in December plays differently from one still chasing a playoff spot.

The Round Numbers

Totals cluster less than spread margins, where 3 and 7 rule. Even so there is bunching around 41, 44 and 47, because those are natural sums of touchdowns and field goals. Crossing one of those with a half point is worth more than crossing a 45.

Pushes and Whole Numbers

If the total is a whole number and the game lands exactly on it, the bet is a push and your stake comes back. A total of 44 with a 24-20 final pays nobody. That is why 44 and 44.5 are different bets, and why the number you get matters as much as the price.

The Total You Bet Is Not the Total That Closes

Totals move a lot during the week, more than spreads do, because weather and the injury report are not settled until late. If you bet an under at 47.5 and the game closes at 45.5, you got two points the better of the market.

That gap is closing line value, and over time it says more about your betting than any single Sunday's results. It is covered in the CLV guide.

How We Measure Our Own

Our engine scores NFL spreads and totals and logs them before kickoff, at the price it saw, so they can be compared against the close afterwards. All of it sits on the tracking page, including the ones that go wrong.

There is no NFL record to show yet, and we would rather say so than invent one. What there is, is the method, visible from the first game.
