What is an Over/Under?

The over/under (also called the "total") is a bet on whether the combined score of both teams will be higher (over) or lower (under) than a number set by the sportsbook.

Example

Chiefs vs. Eagles — Total: 48.5

  • Over 48.5 wins if the combined score is 49 or more
  • Under 48.5 wins if the combined score is 48 or fewer

Factors That Affect Totals

  1. Pace of play — Fast-paced teams push totals higher
  2. Defensive strength — Elite defenses push totals lower
  3. Weather — Wind and cold typically lower scoring
  4. Injuries — Missing key offensive players lowers totals
  5. Venue — Altitude (Denver), dome vs. outdoor

Public Bias on Totals

The public tends to bet overs, especially in nationally televised games. People like scoring and excitement. This creates a slight edge on unders in certain situations.

Advanced Total Betting

  • First half totals — Often offer more value than full game
  • Team totals — Bet on one team's score instead of combined
  • Live totals — In-game totals adjust based on game flow
