You probably know this, but a quick refresher: WAR is that funny composite statistic based on runs: the runs you drive in + the ones you produce on the base paths + the ones you save in the field, all divided by how many runs it takes for a team to achieve a win. (There’s a little more to calculating WAR than that, but it’s the basic idea.) All of this boils down to WAR, or the number of wins you’re worth to your team as an individual.
Statheads assign meaning to WAR as follows. If you’re worth 0-1 wins over the course of a single season, you’re disposable.
