Let's use our example from earlier, but this time let's say you think that Florida will cover the -7 spread. Should you place this bet? Maybe. Yes, this is good value bet and one that you should bet, but maybe not right away. Let's say you think the public is improperly going to dump a lot of money onto Arkansas. If this happens and you wait to place your bet, the line might move in your favor. By waiting, you may be able to get Florida at -6.5 to win. This means that if you bet right away, you would only tie if they won by seven points. By waiting, you will win your bet now if Florida wins the game by seven points.
Rotation numbers are standard from sportsbook to sportsbook. The number becomes a way to refer to the game and team without mentioning the teams name. It’s a sort of shorthand. Also, the rotation number allows each book to list the games in the same order—numerically. It is, in essence, a way to keep all of the games that are posted each day and throughout the week organized. That makes it easy for the bettor and the bookie.
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.
