Future Book Betting Pitfalls And How To Avoid Them

By Ross Everett

Sports book futures bets are an increasing popular and potentially profitable way to wager on the outcome of a full season. There's a few common mistakes that novice players make that can be easily avoided by paying attention to the following:

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.

In more theoretical terms, the 'true odds' of a Duke or similar top team winning the tournament are almost always higher than the price offered. Think of it this way--say we're betting Duke to win the national title at 2/1. This means that the Blue Devils would have to win more than 33% of the time to break even. So lets say, for the sake of argument, that we could play the tournament over 100 times. Would Duke come out on top more than 33 of these times? If not, they represent a poor value. Let's say that they win 30 of 100 times. This means that any price under +333 or thereabouts is a poor wagering value.

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.

Simply stated, the concept of value works the same at the bottom of the wagering ladder as it does at the top. Even if you're betting a big underdog at a huge price make sure that it accurately reflects the 'true odds' of the event occurring.

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.
