NFL Over/Under: Odds & Line Movement

Over/Under 101

How Over/Unders Are Calculated

Oddsmakers have many factors when calculating the over/under for a game. A team's talent level, the pace of play, weather, and other factors play into a total. Typically the total has -110 juice on both sides, meaning a bettor has to pay an extra 10 percent extra for every dollar he bets.

The first thing bookmakers are going to do when setting the total is how well a team's offense goes up against their opponent's defense. This is a fundamental way to understand how a total will be set. If a team with a high scoring offense plays a defense that allows a lot of points, then the total will be higher. If the defense has the edge over the offense, then the over/under is set lower.

One thing casual bettors might not factor in is a team's tempo. Tempo usually refers to how fast or slow a team plays. Some teams like to use all 40 seconds in a play clock while other teams run much faster offenses and only use 20. The tempo of an offense will dictate how the over/under listed.

Weather is an essential factor to remember when betting on a total. When the NFL season kicks off in September, the weather is a rare issue as it is still relatively warm out that time of year. Rain is the biggest issue a bettor needs to factor in if the forecast calls for it. Slick surfaces slow down players and affect how many points will be scored.

When it comes to frigid temperatures later in the season, snow and wind have an impact on the total. First, windy games play a big part in the total. With today's NFL becoming a passing league, it is much tougher to throw the ball in windy conditions. Places like Buffalo and Chicago deal with the wind often playing along the Great Lakes, and bettors must factor in the wind depending on the forecast.

One misconception about the weather is during snow games. When the forecast on gameday calls for snow, casual bettors instantly think that fewer points are scored. However, the snow doesn't have the same effect that rain and snow do. Games often play at a normal pace in the snow as long as it isn't windy. Bettors will instantly think under, which creates value on the over.

In the NFL, injuries have a significant impact on a game. If a star player is injured, then the over/under will be affected. A quarterback injury will have the biggest impact on a total. The team has to start a player that isn't as great handling the football on every play. The offense usually moves slower, and the team plays more conservative. Slowing down the game means fewer points on the board, and oddsmakers will be sure to adjust accordingly.

Looking for Value in the Over/Under

After oddsmakers set the over/under for a game, it is the bettor's job to decide whether or not the total has value. Some bettors use statistical analysis to bet on a game where others will use situational analysis to find an edge. Handicapping is the best way to understand why a total is listed as it is. When bettors handicapping, it means they are researching a game to determine if there is value in a line.

A fundamental way to determine the total of a game is by looking at stats like points per game or yards per play. Both stats give a better idea of how efficient offense is at moving the ball and scoring. Also, bettors should look at the opponent's defense. If they are as skilled in stopping offenses, then this is something to take into account.

Also, finding efficiency statistics will help determine how good an offense or defense is. Some stats like yards per game are deceiving. However, if a bettor can determine that a team has a worse yard per game average but more efficient, then this gives the bettor an edge in understanding that the numbers don't tell the whole story.

Tempo also plays a factor in statics. Today, there are stats like plays per game available to bettors to know how many play an offense is running per game. This will play into how well an offense can move the football along with how fast they move. Quicker paced offenses often score more points.

Situational handicapping is when certain aspects of a game change how it will be played. For example, bookmakers might list a total for an NFL game that is still five days away. Leading up to the game, forecasters call for rain during the game. As the week goes on, bookmakers will adjust the total to fit the situation that has come up. Good handicappers will jump on the total quickly before oddsmakers change it giving them more value.

Injuries are another factor that plays into a total. A bettor might realize that the week before, a quarterback took a big hit and was listed questionable the following week. The team tries to cover up the injury, so they don't give their opponent an edge. Veteran bettors will take note and use that information to find value in the total. A weaker quarterback means a less efficient offense, which could lead to a lower-scoring game.

Also, scheduling could factor into the total. If a team is coming off an important Monday night win, then they have less time to prepare along with trying to refocus the following week. The team could come out sluggish the next game, which will put the value on one side of the total.

Overall, there are many ways to find value in a total. The best bettors do their homework and understand the situation and teams to know if oddsmakers put out a good total or not. They pay attention to injuries and understand how teams are playing to know whether or not they'll have a good performance. After doing some homework, a bettor should fire away on the bet that makes him most confident.

Final Thoughts

Over/Under wagers are an excellent way for novice bettors to understand odds and lines. A bettor new to the game might find it easier to predict how many total points will be scored in a game instead of how much a team will win or lose. Betting a total makes a player look at both sides and gets an early understanding of why oddsmakers set lines where they do.

Betting totals isn't easy. However, betting totals gives a player another type of bet to play while also finding an edge in a line. Moreover, bettors will understand the situations as to why over/under lines move and what causes it. As long as beginning bettors don't overexpose themselves, then over/under bets are a great thing to start betting.
