There are many reasons why point spread betting has become the most popular type of wager for football and basketball games. In many football matchups, there is normally one clear favorite and an underdog. But, often times, this can make moneyline bets not worth it to bettors because the odds are one-sided and therefore unprofitable. But, spread bets add more elements to the matchup, making it more dynamic and interesting for bettors, thus making it more popular.
Because you are not betting on an overall winner, just the point margin between two teams, there are more opportunities for bettors. This makes games more interesting to watch as well. In some games, a team may take the lead and it will be a straightforward victory from that moment. However, point spread bettors will be on the edge of their seat waiting to see if the underdog can close the point spread gap. Players get to utilize the entirety of their sports knowledge to predict how certain teams will matchup and what the overall outcome will be.
