Bookmakers use odds to even out the bets, getting gamblers to wager on both sides of the line by leveling the playing field. Although there is overall parity in the NFL, there are teams that are haves and others that are have-nots. Indianapolis is still superior to Cincinnati but when they play each other the bookies have to get about half of the bettors to put cash on the Bengals. This covers the sportsbooks ensuring they’ll make a decent amount of cash on just about every game.
The National Basketball Association (NBA) has always been a staple of the sports betting community. As a part of one of the big four sports, bettors have been working to develop systems to best the basketball betting industry for decades. Some have succeeded and enjoyed the spoils, while some have fallen. Our guess is that most of those who have fallen did so due to a lack of effort, a lack of information, or just no knack for the sport.
That was all before Charles McNeil, a math teacher from Chicago, invented the concept of the point spread. An avid gambler, McNeil created what he called “wholesaling odds” and started his own bookmaking operation in the 1940s. He started out offering this new style of betting on football, but his business model grew to include basketball. McNeil changed the way sports betting was done, and his legacy lives on today in what we now call the point spread.
