The most common type of sports betting is point spread betting. A game's favorite is denoted by a negative (-) sign next to the point spread. The worst of the teams in the game is referred to as the underdog. The bettor wins if this team wins outright or loses by a margin less than the point spread. If they lose, the bettor keeps their money. Some bookmakers will also offer full-game spreads. These are identical to standard spread bets except that the total points scored by both sides are included in the wager. For example, if a football game has an average point score of 40/20, a bet on that game would be considered a half-point spread ($100 stake). But if the game has an average point score of 45/25, then it's a three-quarter point spread ($150 stake). Full-game spreads are useful for games with no clear-cut favorite or loser. In that case, books use statistics to determine who they think will win. For example, if you picked Nebraska to beat Ohio State and the lines moved accordingly, you'd expect one of these teams to cover the point spread. However, neither team was particularly good last season (Nebraska ranked 70th, while OSU ranked 94th), so there's a good chance that won't happen. If that game had been played after week 9, then it would have been a half-point spread because then statistical models would have predicted which team would win.
