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.
Odds for different outcomes in single bet are presented either in European format (decimal odds), UK format (fractional odds), or American format (moneyline odds). European format (decimal odds) are used in continental Europe, Canada, and Australia. They are the ratio of the full payout to the stake, in a decimal format. Decimal odds of 2.00 are an even bet. UK format (fractional odds) are used by British bookmakers. They are the ratio of the amount won to the stake - the solidus "/" is pronounced "to" for example 7/1 "seven to one". Fractional odds of 1/1 are an even bet. US format odds are the amount won on a 100 stake when positive and the stake needed to win 100 when negative. US odds of 100 are an even bet.
As the numbers grow larger each way – the small numbers get smaller or the positive numbers get larger – that indicates that those options are bigger and bigger favorites, or bigger underdogs. That’s particularly relevant when you’re looking at something like the odds to win the Super Bowl. The teams with smaller numbers are deemed as having a better chance of winning and then as the numbers grow larger, those teams are deemed bigger and bigger longshots.
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.
