(Note: this post will not contain any “Adrian Peterson is a stud. The guy is a beast!! I see 2000 yards and 20 touchdowns this year!!” – type fantasy analysis. So if that is the sort you enjoy, please leave now.)
Nassim Taleb has essentially become the white angel on our shoulder when it comes to all things risk related. If you haven’t heard of him, Taleb is the author of “The Black Swan: The Impact of the Highly Improbable”. The book essentially popularizes Taleb’s theories on risk (don’t worry, I promise I’ll bring this back to fantasy football). Taleb uses a string of analogies in the book to make the concept of risk more easily understandable. One of those analogies is the Thanksgiving Turkey. Taleb says that if you are a Thanksgiving Turkey, your view of your entire life is that things are pretty good. Someone is feeding you every day. You have no sense that there is any risk or danger in the world. In fact, your confidence that no risk exists lasts all of the way up until your head is chopped off and you’re served for dinner.
Taleb’s point is that if you’re a turkey, getting your head chopped off and served for dinner is a low probability (though high impact) event. You live your entire life with no measurable occurrences of risk. Then you have one single high impact event that is impossible to predict or measure the probability of it happening. Your perception of what risks exist for you and the reality of what risks exist for you are entirely different – if you’re a turkey.
I think when we try to predict the future in fantasy football we have a similar problem. We can easily be lulled into thinking that no risks exist. Take the case of Randy Moss. Moss went from being the 2nd WR selected in fantasy drafts, a spot that many would characterize as being due to his extreme safety as a pick, to being droppable in leagues. That happened in a mere 8 weeks of time.
I see the same issue with overconfidence every year when it comes to the top picks in fantasy football. Every year the top guys are hyped due to their safety as picks, and every year we see some busts on what were supposedly safe picks. Every year we see guys who were supposed to be extremely reliable, due to years of track records, end up not being reliable and killing our fantasy teams. Our perception of where the risks lie, and the reality of where the risks lie, are often separated by great distances.
Moss’ falloff is a great example because receivers typically hone their craft over years, getting better at things like running routes, using their bodies to shield the ball from defenders, and reading defenses. So they get better each year until late into their careers. They get better until their bodies stop cooperating and then they seem to fall off a cliff. It happened with Marvin Harrison. It happened with Torry Holt. Now it’s happened with Randy Moss.
I have some additional thoughts on this topic that I’ll be expanding to other players, but first I wanted to get out there the notion that our perception of risk is not necessarily consistent with what the risks really are. Don’t be so quick to say a guy is “safe” because safety is a more elusive concept that you realize.
