Sports betting futures wagers can be an entertaining and profitable investment, but there are a number of pitfalls. These are some things to avoid:

Search for the best price: A common mistake is to assume that the price on a specific futures wager position will be the same at every sportsbook. Nothing could be further from the truth. In fact, you’ll often see a greater degree of difference between futures prices from book to book than any other form of bet. This is because that books aren’t as worried about what price other outfits are offering as they are about keeping their own financial position balanced.

Don’t try to pick the winner in a competitive marketplace: This may sound sort of counter intuitive since the general idea of betting on futures is to determine the actual winner but it’s really not. Like everything else, its essential to always be mindful of the value you’re getting. In a futures market with several legitimate contenders at the top the price offered is seldom high enough to properly compensate for the risk you’re assuming. Here’s an example: in a hypothetical NCAA hoops tournament Duke is +200 to win the national championship. They’ve certainly got a shot, but at a payback of only 2/1 its hard to justify a wager at this point with the potential for so many interceding events that can make a championship more problematic. Such events as injuries, a tough tournament draw or even just going into a slump at the wrong time can happen to any team but when you bet a higher priced team–a ‘dark horse mid major at 15/1 for example–you’re getting “compensation” for assuming the “risks” of betting on a proposition with so many unknown variables.

To put this in more theoretical terms, the “true odds” of Duke winning the NCAA Championship are almost certainly higher than the price we’re getting. Obviously, determining the “true odds”, or actual probability of a future event is an inexact science but think of it this way: if the NCAA tournament was played 100 times would Duke wind up winning 50 of those? Given the number of other good teams and the propensity for upsets along the way, its doubtful. For the sake of argument, lets say that Duke has a 33% chance to win the tournament. That means that I wouldn’t consider a bet on Duke to be a good value unless I was getting a price that a) accurately reflected the true probability of their winning and b) gave me some compensation for assuming the “risk of the unknown” inherent in taking the position so far in advance. At +500 I might be interested, but at +200 the value just isn’t there.

Note that the more competitive the market, the more difficult it is to find good value on a favorite. In a smaller field, or in a field with one dominant competitor it can be easier. For example, say the UFC were to have a tournament involving heavyweight champion Brock Lesnar and three male figure skaters. Even if Lesnar was slightly injured, or not at the top of his game he’d essentially have a 100% chance of beating the smaller, effeminate men who are untrained to fight. If a book installed Lesnar as a -1000 favorite in this spot, it could still be considered a good value. It’s never easy to risk a lot to win a little, but from strictly a mathematical standpoint it makes sense.

Don’t try to make a huge profit with little risk: Sports betting provides few opportunities to make a ‘big killing’. It may happen occasionally, but even the big payouts when it occurs doesn’t make chasing big longshots a good value. If you’re serious about sports betting it is crucial to maintain your focus on the underlying numbers and look for value at all times. If you want to take a longshot at a huge jackpot, play the lottery but don’t try to do it at a sportsbook.

On a more theoretical level, a big price alone is no way to justify a wager. The concept of value works the same at the bottom of the barrel as it does at the top: make sure the price you’re getting on an underdog accurately reflects their “true odds” of winning.

Don’t bet one sided props: Sometimes sports books will offer silly bets just to get publicity or in some cases just to be funny. While there may be life on other planets, the ‘true odds’ of a Martian being named to President Obama’s cabinet wouldn’t justify a +5000 line that it would occur.
