In football the money line is often a popular choice for bettors who have been burned by last-second scoring that actually had no actual affect on the outcome of the game. With the money line you just have to hope your team wins rather than cover a point spread. Of course, the one downside is having to risk more money to return the same amount that a point spread bet would net you.
If the bookmaker was only confident enough to give Seattle a field goal’s lead on the Patriots, it was clearly going to be a tight game. Oddsmakers aren’t often that wrong about flagship games like the Super Bowl. All things being equal, it’s likely the betting public would have taken the Seahawks to win the game and have been done with it. But throw in the point spread that gave the Patriots 2.5 points, and the proposition seems more equal.
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).
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.
