If a team is -5 in NFL betting at BetMGM, they're favored by five points. Their opponent, the underdog, would be +5.
To cover the spread (-5), the favorite must win by at least six points. If they win by exactly five points, it would be a push.
To cover the spread (+5), the underdog must lose by four or less points, win the game, or tie (after overtime). If they lose by exactly five points, it's a push.
Overtime is included in the final score that determines if the team covers the spread.
