In 2017 Junior Guerra, Zach Davies, Wily Peralta, Chase Anderson & Jimmy Nelson constituted our opening day rotation. Guerra got hurt opening day & was replaced by Tommy Milone & eventually Matt Garza. Ultimately an outlier season from Anderson, Nelson's breakout (which finally came after 436 mediocre MLB IP) & Davies doing Davies things carried the rotation to a top 10 finish in both runs allowed & FIP based WAR while the team exceeded expectations by winning 86 games & just missing the postseason. In 2018 our opening day rotation was Anderson, Jhouyls, Suter & Davies with Guerra & Miley waiting in the wings injured. The Chacin & Miley signings hadn't inspired much confidence, most thought Chase would regress & Guerra should already be in the bullpen. Ultimately it was an underwhelming group coming in 19th by FIP based WAR & 15th by runs allowed based WAR. Yet, the team exceeded expectations winning the division & made it within a game of the World Series. In 2019 we finally had the long awaited Brewer fan dream. Not one, not two, but three count em three starting pitching prospects, of varying degrees of bona fide-ness, all in the opening day rotation. Many thought it was a risky strategy for a team hoping to contend & it was. Two of the three flopped (plus Chacin) & the rotation, now under the tutelage of Chris Hook, came in about the same as the year before 20th fWAR/15th rWAR. On a team level the projections were once again beat, even if fan expectations were not necessarily exceeded, as the Brewers made the postseason & nearly knocked out the eventual WS champs. So three years, three uninspiring opening day rotations with varying question marks that have ultimately turned in mediocre results (13th rWAR/17th fWAR, 2017-19) yet on a team level we have won the 8th most games in MLB over that span, same as the Cubs & more than the Rays, A's, Cardinals, Braves, etc. What I guess I'm saying is the 2020 rotation has plenty of question marks. I would guess they will not finish the season as a top 10 group. I also do not believe this will deter the Brewers from delivering another summer of entertaining, competitive baseball.
