  • Identify key factors affecting spread calculations, like team performance and injuries.
  • Understand the risks and rewards associated with point spread betting.

The Basics of Spread Betting

In sports betting, a spread, also known as point spread, is a set difference in points for a sports game. Any game may have a -3 spread or a +12 spread. All the number means is how wide the deficit is expected to be:

For example: A +12.5-point spread means X team is expected to win by 13 or more. The betting line there simply means what the final score will be separated by. 

Taking that into account, oddsmakers set these spreads to try to get bets on both sides. Much like an over/under, the betting market sets these metrics with the idea of finding the perfect middle ground and enticing those on both sides to take the bet. 

Their goal is to find the sweet spot that will have supporters of a team convinced they can cover and supporters of the other convinced that they cannot.

On one hand, fans may believe that their team is so good that they can cover the spread. Others may believe their opponent is being underrated and can win the bet even if they lose.

This is where the phenomenon of betting against the spread comes from in online sports betting. 

Calculating Point Spreads

Formulating a point spread is a complex process that combines mathematical equations, statistical analysis, and expert insights. Oddsmakers assess a wide range of factors to determine the expected margin between teams, ensuring the spread reflects the most accurate prediction possible. Key factors influencing the spread include:

1. Team Rankings and Performance

Rankings and recent performance metrics can heavily influence the spread. A higher-ranked or in-form team will often be favored over a lower-ranked opponent, which typically results in a larger point spread.

2. Rest and Scheduling

The amount of rest a team has had can impact performance. For instance, a team playing on consecutive nights (back-to-back) is often expected to perform worse, potentially affecting the spread. Bye weeks in sports like football can also lead to significant adjustments.

3. Home-Field Advantage

Playing at home often provides a team with a competitive edge due to familiar surroundings and fan support, which can shift the spread in their favor.

4. Injury Reports

Injuries to key players can drastically alter expectations, leading to a shift in the spread to account for the weakened strength of the affected team.

5. Historical Matchups

Past encounters between the teams might offer insights into how a game might unfold, affecting the projected spread.

6. External Conditions

Weather conditions, travel demands, and other external factors can also play a role in shaping the spread, too.

Even though these elements continuously evolve, oddsmakers strive to maintain a calculated balance, adjusting spreads based on new information. Some outlets list a team’s record “against the spread” to provide further context about how teams perform relative to these predictions, helping bettors gauge potential outcomes more effectively.

What Is a Negative Spread?

Example of a point spread in sports betting.

The plus (+) and minus (-) signs in the spread matter a lot. The minus sign means a team is favored. With that logic, a negative spread simply indicates how many points a team must win by to cover the bet.

Example 1: If the San Francisco 49ers are favored by 6 points, they need to win by more than 6 for the bet to pay off. The actual margin of victory in the sport, whether it’s by 24 or 4 points, doesn’t impact the team itself, but it’s crucial for bettors.

Example 2: The Charlotte Hornets are favored by 4.5 points against the Washington Wizards. Bettors who place a negative spread bet on the Hornets need them to win by at least 5 points. A win by only 4 points, while a victory for the Hornets, means a loss for those who bet on them to cover the spread.

This element adds significance to every point scored in the game, including during garbage time.

Strategies for Betting on Negative Spreads

Betting on negative spreads is often a dangerous game. Certain sports lend themselves to it more. Here are a few examples:

In NFL Betting

A 3.5 point spread in an NFL game isn’t that big of a deal, since scores are worth 6 and the margin is usually not as close. Even just an extra point is harder to come by in football.

It could very well be a close game, but a close game could feature as much as an eight-point margin, which makes taking the negative spread a bit of a safer option.

In NBA Betting

It’s a lot more challenging to take the negative in NBA betting, since points can come in flurries and scores are worth less. A 9.5 spread in a basketball game can be undone in a matter of seconds since scoring happens much more frequently as well.

Football and basketball differ in that manner, so you want to bet with a full understanding of how sports betting works in a specific sport. 

Risks and Rewards of Spread Betting

Spread betting in sports hinges on the margin of victory, and it can be unpredictable.

For instance: During an NFL game, the Los Angeles Rams, trailing by 10, kicked a field goal as time expired. While the field goal didn’t affect the game’s outcome, it reduced their deficit to seven points, impacting bettors who had the San Francisco 49ers to cover a 7.5-point spread.

Additionally, spreads can change based on player availability.

For example: If Los Angeles Chargers’ quarterback Justin Herbert is injured, the 4.5-point spread in their favor could shift significantly by game day.

While spread betting offers the potential for higher profits due to its inherent risks, it also means the stakes are higher, magnifying both the potential returns and the risk of loss.
