The most prevalent means of sports service marketing is some variant on the theme that so and so is “red hot” and you should therefore pay him your money and follow his plays. The crooked services do this by coming up with all sorts of confusing and contradictory rating systems and hyperbolic descriptions for their games. How many times have you heard a handicapper brag about being “16-2 on his 500 star MWC underdog plays of the month” or saying that his “Southern Conference total of the month is 60% lifetime”?
Basically, the bottom feeders of this industry can slice and dice their statistics all sorts of ways to make themselves seem “hot”. Or they can do what a lot of them do, and simply lie about their performance. When I was first starting out as a sports handicapper there was no such thing as the Internet (at least as it exists today) and I had to rely on a scorephone for line and score updates. This scorephone was sponsored by a group of touts not noted for their veracity, and you had to sit through a few pitches for their 900 numbers before you got to the scores. A bit of a Faustian bargain, to say the least, but it was an effective way of keeping up with scores in the pre-Internet dark ages.
So one night we’re at a party thrown by some kid that we did not like too much. My crew and I were racking our brains to think of some mean pranks to pull on the guy. Someone got the idea to rack up some 900 # charges on our mark’s phone bill. Since there’s no such thing as 900 # directory assistance, I resulted to the only 900 # I could remember – one of the touts from the scorephone that had drilled his digits into my memory through the sheer force of repetition.
For the sake of argument, I decided to write down the tout’s NBA plays. I had less faith in his handicapping ability than I would in a prognostication based on a divining rod or Ouija Board, but since I was not paying for the call I figured I’d just see how the guy did. I wrote down his plays and checked his performance the next morning.
To his credit, the tout went 5-3 on his 8 plays. By any criteria a 5-3 night is a solid performance. Later that day I called the scorephone and waited for the tout to start crowing about his 5-3 night. Much to my surprise, the tout did say a word about his 5-3 night. That’s because he was too buy bragging about his mythical 7-1 performance the preceding day.
Now, I understand that the revelation that boiler room touts like about their performance is on par with “pro wrestling is fake” or “the games at the fair aren’t on the up-and-up” as self evident truths. The point I’m trying to make, however, is that the desire to be the “hot handicapper: is so great that the tout felt he had to embellish a solid performance the night before.
So despite the fact that some handicappers like about their performance, what’s wrong with trying to ride the hot handicapper? Plenty-it’s not only an ineffective way to evaluate a handicapper’s abilities, it also has a number of statistical and theoretical shortcomings.
The simplest way to explain what I’m talking about is to borrow a disclaimer that you’ll hear on every commercial for a mutual fund: “Past performance is no guarantee of future results”. The sports gambling milieu, like those of stocks, commodities and other financial instruments, is a marketplace and subject to a number of the same tendencies of other financial institutions (what economists call “market dynamics”).
The fact that a sports wager’s success or failure is dependent to a degree on the “whims” of a marketplace (of odds and pointspreads) and to a greater degree on other external events outside of the bettor’s control exacerbates what is already a matter of simple logic: what a handicapper does over a period of time (be it a day, week, month or season) has no intrinsic correlation between a handicapper’s performance one year and the next. In other words, the sports gambling marketplace and the random patterns of events that act upon them don’t care if I hit 60% last year. If I don’t do my work, crunch the numbers, get good prices to bet into, and catch a few breaks along the way I may end up beaten regardless of how well I performed in a subsequent period of time.
