How does over/under work in the NFL?

NFL Over/Unders

NFL betting is one of the most exciting and strategic forms of sports wagering, with Over/Under bets playing a significant role in how bettors engage with the game. Whether you're a seasoned bettor or a newcomer looking to get started, understanding how Over/Under bets work and how to use them to your advantage is crucial. 

What Are NFL Over/Unders?

One of the more popular NFL bets includes the Over/Under. Also known as the Totals wager, there is no concern about which team wins – your only goal is to estimate whether the game's points total is over or under a given number.

For example, if an NFL game between the Kansas City Chiefs and the Philadelphia Eagles has an Over/Under line of 51.5, you can bet:

  • Over 51.5: The combined final score must be 52 or more for you to win.
  • Under 51.5: The combined final score must be 51 or fewer for you to win.

The actual result does not depend on which team wins or loses, only the total points scored by both teams.

How to Bet NFL Over/Under Lines

When it comes to deciding which side to take in a game, Over or Under, several factors must come into play. While there is no secret formula to win consistently, solid choices can be made based on the data.

Understanding the Line

Over/Under lines are determined by oddsmakers using factors such as:

  • Team offense and defense: High-powered offenses like the Chiefs can drive up the total.
  • Weather conditions: Bad weather, such as heavy rain or wind, can lower the total.
  • Recent trends: If teams have been in high-scoring games, the line might be adjusted upward.

Each game has a unique total, so it's essential to compare matchups and analyze the line before betting.

Placing a Bet

To place an Over/Under bet:

  • Choose a sportsbook and find the NFL game you want to bet on.
  • Locate the Over/Under (O/U) section.
  • Select either Over or Under and enter the amount you wish to bet.

Odds typically range from -110 to -120, meaning you'd need to wager $110 to win $100 on most bets.

Line Movement and Adjustments

Over/Under lines shift based on betting action and news. If sharp bettors wager heavily on one side, sportsbooks may adjust the total. For example:

  • The opening total is 49.5
  • Bettors place large bets on the over
  • The sportsbook moves the line to 51 to balance action

Timing your bet is crucial—if you like the over, it's best to bet early before the line increases. If you prefer the under, waiting might provide a better number.

NFL Over/Under Betting Strategy

There are several considerations that come into play when creating a viable Over/Under betting strategy. They all need to be considered, but how they come together ultimately depends on how the bettor analyzes the data.

Analyze Team Playstyles

Some teams are always in high-scoring affairs because of potent offenses and weak defenses. Others rely on defense and ball control, which usually creates low-scoring affairs.

  • Good Over Teams: Kansas City Chiefs, Miami Dolphins, Detroit Lions (High-powered offenses)
  • Good Under Teams: New York Jets, Pittsburgh Steelers, Baltimore Ravens (Strong defenses, conservative playcalling)

Consider Weather and Location

Weather plays a massive role in NFL scoring. Cold, windy, or rainy conditions often favor the under, especially in open-air stadiums. Conversely, dome stadiums (e.g., New Orleans Saints, Las Vegas Raiders) promote higher-scoring games due to ideal playing conditions.

Look at Key Injuries

Missing key offensive players at key positions (quarterbacks, star wide receivers) can make the under more attractive, as scoring will likely be reduced. Conversely, a team that will be without stars on defense might yield more points and provide more value to the over.

Pace of Play and Playcalling Trends 

  • Fast-paced teams (Philadelphia Eagles, Buffalo Bills) tend to produce more points. 
  • Run-heavy teams (Tennessee Titans, Atlanta Falcons) control the clock, leading to fewer possessions and a lower-scoring game.

Check how many plays per game teams run, their third-down conversion rates, and red-zone efficiency before betting.

Compare Lines Across Sportsbooks

Line shopping is critical for maximizing value. Different sportsbooks may offer different Over/Under numbers.

  • DraftKings: 50.5
  • FanDuel: 51
  • BetMGM: 50

If you're betting the over, choosing 50 instead of 51 increases your chances of winning or pushing rather than losing.

NFL Over/Under Bets and Prop Bets

Over/Under betting isn't limited to game totals—there are also player props, team props, and quarter/half totals.

Player Prop Bets (Passing, Receiving, Rushing Props)

Instead of betting on the game total, you can wager on individual player performance:

  • Patrick Mahomes passing yards: Over/Under 275.5
  • Saquon Barkley rushing yards: Over/Under 89.5
  • Justin Jefferson receptions: Over/Under 6.5
  • These bets allow you to focus on specific matchups, like a weak run defense making the over on rushing yards attractive.

Team Total Over/Under

Instead of betting on both teams, you can wager on just one:

  • Dallas Cowboys Team Total: Over/Under 27.5
  • Chicago Bears Team Total: Over/Under 17.5

If you expect one team to dominate while the other struggles, betting a team total instead of a game total might be the better play.

Quarter and Half Over/Under Bets

You don't have to bet on the full game—you can wager on specific periods:

  • First Quarter Total Points: Over/Under 9.5
  • First Half Total Points: Over/Under 24.5

These are useful if you expect a fast or slow start but are uncertain about the entire game.

Current NFL Over/Under Betting Trends

NFL scoring trends fluctuate each season based on rule changes, playcalling shifts, and team strategies. Some recent observations:

  • Scoring Decline in 2024: The NFL saw a slight dip in scoring due to improved defensive schemes.
  • Primetime Unders: Thursday Night, Sunday Night, and Monday Night Football games often go under due to conservative game plans.
  • Dome Games Trending Over: Indoor stadiums provide ideal conditions for high-scoring games.
  • High-O/U Games in AFC Matchups: Teams like the Chiefs, Bills, and Dolphins frequently see totals in the 50+ range due to explosive offenses.

Keeping up with these trends can give you an edge in picking the right totals.
