When to use the waiver wire
With draft season over and many owners not looking to trade yet, the waiver wire currently dominates the attention of most fantasy owners. However, there are different, conflicting philosophies regarding proper use of the waiver wire, even among intelligent fantasy players and experts. Today, I thought I'd give you my thoughts on the matter.
Some feel that it is best to be aggressive on the waiver wire throughout April, taking a "shoot first, ask questions later" approach. If a player gets off to a hot start with the peripheral skills to back it up, pick him up and see if he continues. If he doesn't, drop him later.
The problem with this line of thought is that in April (and through much of the first half of the year, honestly), sample sizes are far too small to make any kind of reasonable judgment based off of them. Surely we'd be better off judging a player by the hundreds of previous at-bats he's taken as opposed to a handful in April, no?
Still, every year at least a couple of these April surgers outperform projections and turn in great fantasy seasons. Just one year ago, guys like
In a recent conversation I had with an esteemed fantasy analyst, this analyst expressed the idea that many fantasy players get too caught up in small sample sizes and anecdotal evidence, stating that it is the job of the good fantasy analyst to "drive perceptions back to long-term trends." He said that he didn't understand people who claim "if he regresses, I'll drop him later," because at that point you've eaten three rotten weeks. You would never listen to a financial adviser who says, "If the stock falls after you buy it, you can sell!" Put that way, it seems a little silly that we would even consider such a notion.
Here's why I feel differently, though. Baseball players, as much as we may treat them like stocks, are not stocks. They are different and follow a separate set of rules.
The primary cost of a stock is the acquisition cost. You pay a certain amount of money, you acquire the stock, and your return or loss is fully dependent upon its future performance.
In fantasy, however, you can hedge against (or eliminate) the risk of uncertain future performance in your waiver wire pickups. In fantasy, the primary cost is not the acquisition cost (unless you're in a FAAB league or must use a high waiver claim -- these are leagues I'll discuss next time) but, rather, the activation cost.
In fantasy, the only acquisition cost is the worth of a single roster spot (most often the last spot on your bench). You can bench your pickup for three weeks to see how he does without incurring a single additional cost. Only once you activate him do you start to incur additional risk and additional costs (should he fail).
In the stock market, you can't pick a stock and say that you're going to watch it for three weeks before deciding whether or not you wanted to buy it at the original price. In fantasy, however, we can do just this by sitting the player on our bench.
In addition, the last player on your bench will often be an unspectacular veteran player worth only a couple dollars. The cost of losing this player is small because 1) there are likely similar, interchangeable players available on the wire to grab in case your high-upside pickup flops and 2) the high-upside pickup's value might not be much worse than this player's value anyway.
While picking up a player for your bench sounds like a great idea, in some leagues you don't have a bench or simply don't have room on it. If, for whatever reason, you must start the pickup, it still might be worth it to take the gamble. Take a look at the following scenario.
Let's say we pick up
Now let's set up a hypothetical scenario in which Maybin has just two distinct possibilities: playing to his -$7 projection or becoming a $25 player (value dispersed evenly throughout the season). In this case, Maybin would need to play up to his $25 value five times out of 100 in order to break even on the pickup.
So the question then becomes, do 5 percent of April pickups post $25 seasons? This question would take a more in-depth study than I have time for now, but I would imagine the answer is a resounding "yes" if we only include players who are showing marked skill increases (after all, if a player isn't doing this, he's just getting lucky and shouldn't even be considered).
The scenario I depicted above is just one possible scenario that was simplified a great deal. For your fantasy team, it isn't enough to simply use that 5 percent figure and make pickups based off of it. There are a number of factors that really need to be considered:
• Projected value of pickup
To help you decide the necessary probability for your own pickup, I've put together a (very) simplified calculator that will run you through my scenario above and give you a rough estimate of the necessary odds needed to make a pickup worthwhile. You can download it by clicking
Overall, I think it is wise to make frequent use of the waiver wire in the early portions of the year. Of course, every league is different and every team is different, and in some situations this will not be the best strategy. You should examine your own specific situation and then decide upon the best course of action.
In leagues that allow you to bench your pickups, however, it is almost always a good idea to be aggressive early if you have an easily replaceable player that can be dropped. The cost is very small and the reward is huge.
Next time, I'll talk a little about handling the waiver wire in leagues with FAAB bidding.
