Spreads or point-spreads are the numbers next to the teams. The lying points of the teams are denoted by a negative (-) symbol. The underdog team is gaining points, which is symbolized by the plus (+) sign, which is not shown on the board but is represented by the following team on your betting ticket or slip. If you have any questions about what these symbols mean, check out our betting terms page. American football uses different symbols than other sports. In college football, there is a spread between two opposing teams' odds. If one team is given 30 points, then its opponent is given 0 points. A minus sign is used to indicate an underdog while a positive sign is used for an overdog. In addition to this, there are three types of players on a football field: quarterbacks, running backs, and wide receivers. Each type of player is given a number to identify them easily on the field. Quarterbacks are numbered 1 through 9 while running backs and wide receivers are numbered 10 through 17. These numbers do not indicate how many yards each player can run the ball or catch passes; only their position on the field is important for that purpose. College football uses a complex formula to determine who will receive the ball first during each time out.
