  • Methodology

    To determine the best underdogs and favorites to bet on across the NFL, NCAAF, and MLB, Action Sports analyzed results over the last three seasons, and calculated the overall winnings and winning percentages if you were to have placed a $100 wager each time a team was the underdog or favorite.

    For MLB, data was collected from the start of the 2019 season to July 20, 2022. A team was considered the ‘favorite’ if they were given odds of at least -200 before a game.
