In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value. The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
Moneyline (ML) – form of wagering typically used in baseball and hockey, which replaces the point spread, but also popular in basketball especially for picking underdogs. The team you choose only has to win the game, not win by a certain number of points. The negative value still indicates the favorite (-150) and the positive value indicates the underdog (+130). It's easiest to picture the number 100 sitting in the middle of these two values. For example, if you want to bet a -150 favorite, you would wager $150 in order to win $100. On the underdog, you would risk $100 and win $130 if the underdog wins. It's a simple way to have the risk-reward scenario.
The general purpose of spread betting is to create an active market for both sides of a binary wager, even if the outcome of an event may appear prima facie to be biased towards one side or the other. In a sporting event a strong team may be matched up against a historically weaker team; almost every game has a favorite and an underdog. If the wager is simply "Will the favorite win?", more bets are likely to be made for the favorite, possibly to such an extent that there would be very few betters willing to take the underdog.
That was all before Charles McNeil, a math teacher from Chicago, invented the concept of the point spread. An avid gambler, McNeil created what he called “wholesaling odds” and started his own bookmaking operation in the 1940s. He started out offering this new style of betting on football, but his business model grew to include basketball. McNeil changed the way sports betting was done, and his legacy lives on today in what we now call the point spread.
Which brings me to my next point. If you are serious about getting into sports betting, it is vital to have more than one sportsbook to make a wager at. Shopping around for the best lines will help your bankroll and you will be able to turn a bigger profit. If you see a pair of sneakers for $110 at one store, and the exact same pair is $102.99 at another store - which store are you buying them from?
Sometimes with NFL odds you’ll see a spread posted as a whole number. Decimals or fractions are usually utilized to ensure there won’t be a tie. If in our example the spread was reset to 10 with the Colts favored and they win by 10, then the game is considered to be a tie, which in betting terms is called a push. If there is a push all bets are off and the sportsbooks return all wagers back to the bettors.
All this means to someone betting on New England is that in order for them to win their wager the Patriots must win by more than four points. For another bettor placing his money on Seattle, the Seahawks must either win the game outright or lose by less than four points. If the outcome of the game were to be decided by exactly four points, it what result in what is called a “push” where both bettors would neither win or lose their wager.
One of the most basic concepts when it comes to betting on sports, especially football and basketball is the pointspread. Even people that do not bet on sports understand what it means when they read or hear that New England is a seven-point favorite against Miami. While reading a pointspread and understanding what they mean is a very basic sports betting concept, there is still more to these numbers than meets the eye.
Often big games will have "proposition" bets on things not directly related to the final score of the game. These are usually abbreviated to "prop" bets. For example, in football whether or not the first score will be a touchdown. In baseball whether a run will be scored in the first inning. In hockey/soccer, whether anybody will score a hat trick. The odds on these are expressed like point spread bets. For example, as I write this the Golden Nugget has the following proposition bet on Super Bowl 49:
You may often notice that the spread is sometimes set at an even number such as 3, 6 , 10, etc. In this case if the favored team won by the exact amount set for the spread the bet would be pushed, and all bets would be returned. For example, if the Patriots were 3 point favorites and they won by a FG (3 points) than this would results in a push, meaning no matter which side you bet on you would get your money returned to you.
Sometimes a line will move far enough to create a “middle” opportunity. Say the Texas Longhorns end up facing the Wisconsin Badgers in the first round of March Madness. If you have Texas early as a 5-point favorite, and I move the line to Texas –7 later in the week, then you can also place a bet on Wisconsin +7. If Texas happens to win by six points, both your bets cash in. Texas winning by either five or seven gives you a win and a push. Any other result creates a win and a loss, so you’re only risking the vigorish.
Futures betting also is offered on the major events in horse racing, such as the Kentucky Derby and Breeders' Cup. In horse racing futures, if your horse does not start the race due to injury or any other reason, you lose the bet -- there are no refunds. On the other hand, the odds on your horse racing futures bet also are "locked in," regardless of the horse's odds on race day.
If you'd rather not deal with point spreads, you can do a "Money Line" wager, which is whether the team/player you bet on wins or loses. You will see "Hawaii Tech +150 or Alaska Tech -140". This means if you bet on Hawaii Tech, if you bet $100, you would profit $150 (returns $250), while to win $100 on Alaska Tech, you must put up $140. Those ratios work whether you're betting $100, $10, or any other multiple of money.
This is a very common occurrence throughout the sports betting industry. Sportsbooks have the right to shift the spread or odds for any given match prior to it starting. Many factors play a huge role in this decision, and they include injuries, weather, the volume of bets on one side, and anything in between. Depending on the time you place your wager, the bettor may also have an advantage or disadvantage based on which way the spread has shifted.
While the National Basketball Association (NBA) was once active in preventing sports betting law relaxation, current NBA Commissioner Adam Silver became the first major sports leader to break from previous administrative opposition to gambling. In 2014 he stated in a New York Times op-ed, "I believe that sports betting should be brought out of the underground and into the sunlight where it can be appropriately monitored and regulated." In 2017, with support for legalization growing, he confirmed his belief that "legalized sports betting is inevitable".
The NFL spread (betting point spreads is also known as betting ‘sides’ since you are picking one side to win the game) acknowledges that not all teams are created equal. If they were, we wouldn’t need NFL point spreads at all – teams would be so evenly matched that every game was a toss-up (or a pick em in football parlance). Simply picking the winner would be enough of a challenge.
