The Myth of Ceilings
Tonight, the 2016 MLB draft kicks off, with the first couple of rounds being broadcast on MLB Network (and MLB.com) starting at 7 pm eastern. For the next few days, teams are going to make their best educated guesses as to what players might develop into in four or five years, and down the line, we’ll look back at these few days as a big turning point for some organization. Someone is going to hit a home run in the draft tonight, and end up with a franchise-altering class of talent that could propel them forward for years to come. Teams put a lot of resources and energy into trying to make their picks as effective as possible because the long-term impact of quality drafting can be tremendous.
But the reality is that we’re not going to know, tonight, who is hitting a home run as they’re taking their swings. The draft is an exercise in forecasting, but it’s the most difficult kind of forecasting to do; projecting long-term futures based on incomplete or unreliable information. At the very top of the draft, there’s usually enough information to provide some confidence that the players being picked are the cream of this particular crop, but beyond those first few picks, it becomes very difficult to parse the differences. This isn’t a knock on scouts or scouting; it’s just that this particular job of identifying future production so far out is just really hard.
But, interestingly, even with the tremendous uncertainty that goes along with these picks, one term has stuck in the draft and prospect lexicon that suggests that we know more than we actually do, and you’re going to hear that term a lot tonight. For almost every pick, you’re going to hear about a players “ceiling”, or upside, or some other term for the upper limit of his potential. Big guys with big fastballs are given heigh ceiling grades, and diminutive college hitters with contact skills but lacking in power will be labeled as role players or utility guys, and by and large, you’ll find a lot more high-end players in the first group than the latter one.
But when you look at the current major league leaderboard, it should become pretty clear that the idea of an actual ceiling for any player is a significant overestimation of our ability to project their skills this far out.
