Yesterday, I created a model of agent pricing using projected 2014 WAR as the only variable. As I noted in the post, I would classify this model as more of a toy than a rigorous attempt at analyzing the market, as we know there are plenty of factors beyond next season’s performance that influence the size of a free agent contract. Ignoring age and health are obvious flaws, as both are significant factors in contract size, especially when forecasting how many years a player might sign for. And we know that the market pays a different price for offense than it does for defense, reflecting some of the uncertainty that the defensive evaluations have relative to our ability to measure offensive production.
So, before I say any more about this model, let’s remember that this was essentially designed as something like the Marcel projections for salaries. Tom Tango built the Marcel projections as something of a baseline forecast, using very simplistic adjustments and ignoring things like park factors in order to show the bare minimum that a projection system should be able to accomplish. Likewise, I’d say that any serious attempt at evaluating the free agent market should be able to do better than what this basic model can do. This system is as simple as it gets — without being completely wrong, anyway — and we can almost certainly do better, but doing better comes with added complexity, and it’s still nice to have a simple, easily explained baseline to measure other forecasts against.
That said, let’s see what this basic pricing model — naming suggestions welcome, by the way — spits out for a dozen of the more notable 2015 free agents. For now, let’s ignore the future and pretend that these 12 players were free agents this past off-season, and see what the model would have forecast for them as 2014 free agents. As a reminder, we’re using a hybrid ZIPS/Steamer WAR forecasts, and the model multiplies projected WAR by five to estimate annual average value and projected WAR by 2.0 (for 3+ WAR players), 1.5 (for +2.0 to +2.9 WAR players), or 1.1 (for 1.0-1.9 WAR players) to estimate the number of years a player will sign for.
Because I selected 12 of the more notable pending free agents, we’re only looking at players with either a 2.0 or 1.5 multiple, as they’re all projected as above average performers for 2014. On to the forecasts:
