Managing A Fantasy Baseball Team Is Sorcery
This is FanGraphs which means we’re all predisposed to translating reality into numbers. In our world, every event on a baseball field has a run value, and we can assign credit for these events to specific players. We like things to be tidy. A 3.0 WAR player is better than a 2.5 WAR. It’s right there in the numbers.
Except… well… per Dave Cameron, WAR comes with a +/- of about 1.0 over a full season. These are estimates. When comparing a three-win player with a 2.5-win player, it more accurate to say that there’s something like a 60 to 80 percent chance that the three-win player was better. The math is even fuzzier when comparing players of different positions. Especially pitchers and non-pitchers. And let’s not get started on who will be better. Ooh boy.
