If you bet the Cowboys -7 and they win by more than seven points, you win your bet. For example, you can bet the Dallas Cowboys as a -7 point favorite to beat the Green Bay Packers or the Packers as a +7 point underdog. In terms of the spread, the ' - ' always refers to the favorite and the ' + ' always refers to the underdog. The plus (+) and minus (-) in sports betting can refer to either the point spread or betting odds.
