The New England Patriots are currently the favorites to win Super Bowl 53. The point spread opened with the Rams installed as a one-point favorite following the AFC Championship Game, but before the end of the night, the Patriots were a two-point favorite at most sportsbooks. The line has climbed to 2.5 points at most sportsbooks, with a couple going up to three points.
Many people will say that the odds on a spread bet are even, paying 1:1. But this is not true. The actual odds are 0.90:1. For every dollar bet, you can win 90 cents. When checking out the spread, you’ll usually see a number listed next to each spread. That number, which is your stake, is posted as -110. This number tells you how much you have to bet to win $100. If you put $110 on either team, you stand to win $100. If you bet $11.00, you can win $10.00. Every NFL point spread works this way.
This is because bookmakers are in business to make a profit, so they effectively charge a commission for taking wagers. This commission is known as the vig, short for vigorish, and it's one of the ways that bookmakers stay profitable. They don't charge it just for points spreads and totals either, as it's built into the odds for every wager that they offer.
Spreads are frequently, though not always, specified in half-point fractions to eliminate the possibility of a tie, known as a push. In the event of a push, the game is considered no action, and no money is won or lost. However, this is not a desirable outcome for the sports book, as they are forced to refund every bet, and although both the book and its bettors will be even, if the cost of overhead is taken into account, the book has actually lost money by taking bets on the event. Sports books are generally permitted to state "ties win" or "ties lose" to avoid the necessity of refunding every bet.
Spread – also known as the line or point spread, it is generally thought of as the predicted margin of victory for one team. In reality, it's a number chosen by the oddsmaker that he feels will encourage an equal number of people to wager on the football underdog and the pigskin favorite. The negative value -13.5 indicates that team is favored by 13.5 points. The positive value +13.5 indicates that team is the underdog by 13.5 points. Betting on the favorite means the team must win by at least fourteen points to cover the spread. The underdog team can lose by thirteen points and still cover the spread.
You may have heard the term “covering the spread” or the phrase “betting against the spread.” This means that if the favorite team wins an event with the point spread taken into account or that the underdog team wins with additional points, they have covered the spread. If the Packers win that game by more than 7 points, they have covered the spread.
"There’s only so much discretionary income in the Commonwealth, and if this new form of betting taps into it, we feel our sales could be negatively impacted, which in turn could effect proceeds to the Commonwealth," Polston said in an email. "As those proceeds fund college scholarship and grant programs — including every dollar of the popular KEES scholarship — there’s a lot at stake here."
When betting off the board a calculation will be made according to the odds on each event in the parlay. You will win the same amount as if you bet each event separately and parlayed all winnings as you went. An exception is if every event you pick is at -110 odds, in which case predetermined nice round odds will be used. Except for a three-leg parlay, these preset odds are not as generous as if the calculation method were used. For this reason, it is a good idea to have at least one event in the parlay that isn't -110, which will force the calculation method to be used.
In November 2014, a poll found that there had been a major shift in attitudes towards sports betting in the United States, showing that 55% of Americans now favored legal sports betting, while 66% of respondents agreed that this should be regulated by state laws, as opposed to federal legislation. The poll also suggested that 33% of respondents disagreed with the notion of legalization.
Major League Baseball (MLB) Commissioner Rob Manfred has also advocated the league changing its stance on sports betting, with both Manfred and Silver noting that the scale of illegal sports betting makes opposition to betting meaningless. He also stated a willingness to "try to shape" any future legislation at federal level. This was noted as a marked contrast to former Commissioner of the MLB Bud Selig, with Manfred going beyond tacit approval and stating, "There is this buzz out there in terms of people feeling that there may be an opportunity here for additional legalized sports betting."
The concept of betting on totals, or Over/Under (O/U), is quite simplistic. The bettor wagers on whether the TOTAL points scored in a game will fall over or under a pre-determined number set by the sportsbook. Much like the point spread, game totals can be swayed by public opinion. The example below, from the SI Archive, shows the opening totals line for Superbowl XLV:
Point Spread: The point spread remains the favorite way to wager on pro football, regardless of how many new forms of wagering come on stream. ItÂ’s called the line or spread and itÂ’s known as betting Â‘sides.Â’ The common misconception is that Las Vegas sets the spread as its best guess at the margin of victory. But really, it's a number they feel that is a perfect balance and will see an equal number of people to bet the underdog as on the favorite. A negative value like -6.5 means that team is favored by 6.5 points. So deduct 6.5 points from their total score. A positive value on the same game would be +6.5 (add 6.5 points to their final score) and would make that team an underdog of 6.5 points. The favorite must win by at least seven points to cover the spread. The underdog can lose by six points and still cover.
