That would be the point spread on the game. If a team is + 5.5 it means they are “getting’’ 5.5 points. If a bettor places a wager on the team + 5.5 than that team can’t lose by six points or more or the bettor will lose his bet. Oddsmaker will often add that .5 point to ensure that the game does not end in a tie, or a push. Let’s give an example. If the New England Patriots are playing the Pittsburgh Steelers and the Pittsburgh Steelers are + 5.5. A bet on the New England Patriots means they must win by at least six points for the bettor to collect. If the bettor wagers on the Pittsburgh Steelers he, or she, can collect if the Steelers win the game outright or lose by five points, or less.
