Let’s Talk About the Brewers’ Mediocre Projection
By most measures, the 2017 season was a very good one for the Brewers. On the heels of back-to-back sub-.500 seasons, the first of which saw them shift into rebuilding mode, they spent over two months atop the NL Central, from mid-May to late July, and remained in the Wild Card hunt until the season’s final weekend. Their 86 wins and second-place finish in the NL Central represented the franchise’s best showing since 2011. They made a big splash in late January, signing free-agent center fielder Lorenzo Cain and trading for left fielder Christian Yelich. They made some lower-cost moves as well, most notably adding a solid starter, Jhoulys Chacin, to a rotation that finished in the NL’s top five in ERA and WAR.
It’s not unreasonable to think that those improvements would put a team that missed a playoff spot by a single game in the thick of this year’s race. Yet, as of publication, the Brewers are projected to finish just 78-84. What in the name of Bernie Brewer is going on?
It bears repeating that projections are not destiny and that, at the team level, the error bars on a given year of preseason projections tend to average six to eight wins in either direction. The 2017 Brewers were one of those teams that push such averages higher, because as of Opening Day last year, they were forecast to win just 70 games. In terms of overachievement, they matched the Diamondbacks (77 projected wins, 93 actual wins) for the majors’ largest discrepancy; the Giants, projected for 88 wins but finishing with 64, had the largest discrepancy in the other direction.
