Key Numbers That Every Sports Bettor Needs To Know

What Are Key Numbers?

Key Numbers is actually a very simple concept to grasp. They represent the margins of victory in sports contests that are most common. Most NFL games usually end up being decided by 3 points. As a gut feel, one might even say this is the most usual or common margin of victory, and well... that would be correct! However, shrewd handicappers who set the lines or the spreads for games, have developed this theory further, by calculating the exact percentages, and setting their lines consequently.

Herewith an actual example in the NFL - Over the past 3 seasons the following results have been recorded:

Most Common Margins Of Victory - NFL

Margin Of Victory	Occurrence as a %
1 point	4%
3 points	17%
4 points	4%
6 points	5%
7 points	10%
10 points	5.5%
13 points	4%
14 points	4%

Key Numbers - Ever wondered why key numbers matter so much if one wants to be on sports? Has a bet you made ever been lost by 0,5 pt or 1 pt ? And did you think you were really unlucky? Well, you were not...really, just outplayed by the Vegas handicappers, and if you had shopped around for the best line you could have stopped the loss from happening as well!. When a line is set at 3,5 and a punter wants to bet the favorite, it is imperative that he find a line offering that team at 3. If he can't get that price, he has to query the value of the bet. The same will apply when betting the underdog in the NFL @ +2,5. The half-points in betting, especially around 3 and 7 are critical. Hopefully, this table will help in future when you bet on the NFL

This article is only really applicable for the NFL.

Key Numbers in the NBA and NCAAB are very different, and generally play a less important role. We continue this discussion next week with a look at Key Numbers in other sports.
