NFL betting odds, also referred to as the “line,” and the “number.” Amongst other jargon, is the number posted on the NFL odds board rotation that evens the difference of mass appeal between the teams, making them roughly equal in the eyes of the gambling masses. The favorite will have a minus sign and number next to them while the underdog will have a plus sign and that same number next to them. The number is the NFL betting odds assigned by the NFL betting odds makers. For example, if the Dallas Cowboys are hosting the New York Giants and are favored by six-points the NFL betting odds board would read Dallas-6 and New York+6.
