Remembering Odds Lines

Making an odds line seems kind of anachronistic doesn't it? Late money, steam, big money in the pool, meh. 

But, smarter-people-than-I like Mark Cramer who wrote wonderful books on the subject, were not blowing smoke. Even today, it reminds us how to be a better player. 

Take for instance the perennial 15 time never winner. "No shot, the horse doesn't want to win" we often say. This may be true, but only to an extent, because each horse in a specific event has a chance and there's no such thing as "no shot". Everything has a set of odds associated with it. 

Race 5 at Colonial today is a good example. The 5 and 9 have the numbers to be good, but their records are 0-23 and 0-31. My immediate reaction is to say "no shot", but of course both horses do have one. Maybe with speed figures they are 4-1 each fair, and I will make them 6 or 7-1instead. 

I do this often with driver or jockey changes. We all know these changes can signal intent of the trainer, so it's important to look at it. But a good jockey to another good jockey is often meaningless, even though in our mind's eye it might mean "no shot" if we're not a fan of the change. 

Even a poor driver to a good one can be much ado about nothing, when we put it into the concept of a fair odds line. 

I remember looking at driver changes in harness racing a bit ago. I don't know how many people will jump on a horse when Ake Svandstet or Trond Smedshammer hand the lines to a star driver like Dexter Dunn, but the numbers don't prove this a very smart wager. The win percentage, over a fairly large sample, doesn't increase much at all, and the ROI is worse with the new driver, because it is such an obvious handicapping factor. 

We all know Dexter is better than those two drivers, and I, like you adjust our odds lines, but we tend to do it too much. The horse is not 8-5 with Dex and 12-1 with Ake. That's ridiculous, we know it's clearly much closer, and the empirical numbers bear this out. 

When we think of handicapping in chances of each horse, we think of the event in a set of odds.  Thinking this way keeps me focused on the present, and when the blinkers don't go on too early where I avoid the "no shot" thoughts, it helps me see the entire race better.

Have a nice Monday everyone.

At the Meadowlands this year I did chart driver choices. A little different than what you are saying in the article. Bottom line is that horses that were chosen off of won about 5% overall and returned .53 on the dollar. These horses were just awful plays.

I had not heard of Mark Cramer before reading this blog entry. Thank you for that.
