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.
This arrangement tells us a lot: which team is home (listed on bottom, in this case the Seattle Seahawks), which team is the underdog (listed with a plus sign next to their name, in this case the New England Patriots), we know which team is the favorite (listed with a minus sign next to their name, in this case the Seattle Seahawks), and we know the point spread (2.5 points).
Using the Patriots-Rams Super Bowl matchup as our example, the Patriots are listed by most sportsbooks as a 2.5-point favorite. The Patriots are listed at -2.5, while the Rams are listed at +2.5. If you bet on the Patriots to cover the spread and they win by three points or more, you win. If you bet on the Rams to cover the spread and they lost by less than three points or win the game, you win.
The sign in front of the number indicates whether placing a wager on that outcome will pay out more money then you have wagered or less money then you have wagered. If the odd is negative (-) it means that outcome is more likely to happen and placing a bet on that outcome would payout less than the amount you wagered, while a positive (+) odd shows that the outcome is less likely to happen and it would pay out more than the amount you wagered.
Money Line: More common in baseball and hockey, pro football moneylines are growing in popularity. There is no spread, so your team just needs to win the game, not win by a certain number of points. The negative value means a favorite (-190) and a positive one indicates an underdog (+170). Picture the number 100 sitting in between these two values. Example: if you want to pick a -190 favorite, you must risk $190 in order to win $100. To back a +170 underdog, you put up $100 and win $170 if the dog wins. In some cases, betting moneylines is actually better value and can provide a bigger profit for less risk.
