What do we have here? For an explanation of this series, please read this introductory post. As noted in that introduction, the data below is a hybrid projection of the ZIPS and Steamer systems, with playing time determined through depth charts created by our team of authors. The rankings are based on aggregate projected WAR for each team at a given position.
Yes, we know WAR is imperfect and there is more to player value than is wrapped up in that single projection, but for the purposes of talking about a team’s strengths and weaknesses, it is a useful tool. Also, the author writing this post did not move your team down ten spots in order to make you angry. We don’t hate your team. I promise.

Look, I understand full well this is probably the least-anticipated part of the series. This is a look at only half of the teams, and it’s looking just at relievers, who pale in perceived importance relative to starters. Also contributing to this is the idea that relievers, and therefore bullpens, are almost hopelessly capricious and unpredictable. I’ll grant you that to a certain extent, but it’s also exaggerated — we have a decent idea of reliever and bullpen talent. Relievers don’t get injured a million times more often than starters. The biggest thing is that, because of the limited single-season reliever sample sizes, there’s just room for more variation around true talent. But that doesn’t mean we can’t have good forecasts. This is a worthwhile endeavor, and sometimes a strong or weak bullpen can make all the difference to a team’s postseason chances. Come with me on a journey! It is a journey with numbers and words, where we discuss the best of the projected bullpens.
