Future Book Betting Pitfalls And How To Avoid Them

By Ross Everett

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

Don't bet at the first place you look: In other words, shop around for the best price. This is essential to all aspects of sports betting, but especially important with futures wagers. You'll find more disparity between prices from book to book on futures than any other betting proposition. From a theoretical standpoint, a little work can yield much better value. From a practical standpoint, that means a higher payout should you win. The reason for this is that individual sportsbooks' aren't as worried about what the other guys are doing as they are with most other bets. Once the futures "market" is set books move the lines almost exclusively on their own financial position. The market simply doesn't respond as quickly to futures wagers as it does to individual game lines so it is essential to do the extra work to get the best price on your proposition.

In a competitive field, don't obsess with picking the winner: This may sound like a strange concept, but once you understand the theory behind it it makes perfect sense. In a large field--the NCAA basketball tournament is a perfect example--the top few favorites are invariably priced at odds that are less than the 'true odds' of them winning. On the other hand, there are always teams that fly 'under the radar' available at higher prices that present a betting overlay.

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.

In a less competitive field, there can be instances where even a big favorite is a good value. For example, lets say a book was to take action on a bikini contest between a Victoria's Secret supermodel and three members of the Pittsburgh Penguins. The model would essentially be a 100% probability to win the contest, meaning that even a high chalk price would be a good value. Risking a lot of money to win a little is a tough thing to justify, however, even if the math makes sense.

Don't go for the big killing: Sports wagering is not a good arena in which to make a 'big killing'. It may happen from time to time, but it is extremely rare. A perennial doormat can come out of nowhere to win a championship at a big price, but the fact that it happens from time to time doesn't make it a good value. If you're a recreational player and want to throw a few dollars at a big long shot, no real harm. If you aspire to any degree of seriousness as a sports better, however, you need to maintain your discipline and commitment to value at all times. If you want to hit a big jackpot play the lottery or the slot machines, but don't try to do it in a sports betting paradigm.

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 futures or propositions: Though many of these are not futures per se, a lot of sportsbooks offer silly propositions on nonsport events as a way to get publicity, or just to be funny. Its important to make a distinction between this type of silly bet and more realistic nonsport propositions which frequently present good wagering value. Im talking the really outlandish stuff here. Not too long ago, a sportsbook posted a line on Martians landing on earth and painting the White House red by the end of the year. The "YES" was +2500 or thereabouts, which is far from reflective of the "true odds" of this unlikely event. Even if you're the type that collects classic Art Bell shows on tape and believes in UFOs you wouldn't place the probability of this happening at more than a fraction of a percent. The book only offered the "YES" side of the proposition, meaning that you couldn't lay even a huge price on the more likely outcome. Another book had a futures offering for what would happen first with Ashton Kutcher, Demi Moore and Bruce Willis. All of the options were very unlikely--Ashton and Bruce fighting on PPV and my favorite--and the longest odds--Ashton, Bruce and Demi hopping in bed together and releasing a porno video documenting the event. You'd receive a sizable payback if any of the events ever transpired, but I'm not exactly sure how to compute the "true odds" on "when pigs fly.
