The second way is “eyeballing it.” If two teams play 10 times, how many times do you think a certain team is going to win? If you say they are going to win 6 times, then you think they are going to win 60% (6/10) times. Looking at it as a series of multiple games makes it a lot simpler for you to grasp and predict. Then, you just convert that number to a percentage and compare it with the implied probabilities offered at the sportsbooks. If there is value, go for it.
If you were correct though but getting paid at the sportsbooks rate, you would lose the bet 55.6 times (-$5560) and win the bet 44.4 times (44.4 x $250 = $11,100). You would profit over $5,000 for betting on bets that you thought you were going to lose! This is finding value. Value bets are great as a part of a long term winning strategy and are the key to conquering the “simple” moneyline/win bets.
The most important takeaway is the actual pointspread, which is seven points in this example. The plus sign is always in front of the spread for the underdog and the minus sign is used to signify the favorite. Next to the pointspread in this example is (-110). This number reflects the actual commission (or juice) that the sportsbook is charging to book this bet. If you wager $100 on New England as the favorite and the Patriots go on to win my more than seven points, you would win $100. If they won by fewer than seven points or lost the game outright, you would owe this betting outlet $110. If New England wins by exactly seven points, the bet is considered to be a PUSH and no money exchanges hands. You only pay the 10 percent commission on losing bets.
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.
