Many online sportsbooks have a wide variety of props. NFL games are filled with dozens of markets and hundreds of betting options, and the popularity of these props increases in the postseason and Super Bowl. Players are the most popular props, as well as over/under bets and winning margin markets. Propositions can be both long-term and short-term. For example, you can bet on whether a certain player will score a touchdown in the game, or on the game’s total points.
