A +7 spread is very commonly seen in the NFL due to the scoring of a touchdown and a successful extra point. If the spread is set at +7, the underdog must either win the game outright or lose by fewer than seven points in order to cover. For the favorite to cover, they must win by more than seven points.

Put simply, it's a bet on which team or player will win a game or contest, regardless of the final margin. Unlike other types of bets, such as a point spread bet, a parlay or a teaser, moneyline bets keep it simple: if you place a straight bet on the winning side, you'll cash your ticket.

If the moneyline is +200, it means the team is the underdog and you could win $200 if you bet $100. What happens if you bet $100 on a moneyline? If you bet $100 on a moneyline, you might win some money or lose your wager. If the odds for your moneyline bet were +100, you would profit $100 if the team you backed won.
