When it comes to NFL Betting lines, players have to be just as thorough with paying attention to numbers as they are with paying attention to factors such as injuries and other trends. Key numbers indicate the margin of victory most common in the NFL, and they can tell players a lot about what the pay head bookies are trying to do with the spreads for particular games. Three points is the most common final score by a long way, with seven the next in line. Other key numbers in football are four, six, and 10, so keep an eye on them when they come up.

About 16 percent of NFL games fall on the number three, compared to 8 percent that fall on seven, and 6 percent with 10 or six. When a sports betting line for a given game is close to that number just missing on either side, then the bookies is apparently looking to lure you in to one side. For example, if the most common final margin for a game is three, than by listing a team at minus-2.5 or plus-3.5, the bookie is trying to entice you to roll with that number. When it comes to buying points or teasing games, these numbers have to be considered the most attractive to work with as you then have the ability to manipulate the system. Those half-points could end up being crucial in the end, so make sure that when you play you take advantage when those numbers come up.
