The year 2018 wasn't that long ago. It really wasn't, despite how it seems. The Red Sox beat the Dodgers in the World Series that year and while it feels like an epoch has passed since that happened, the highlight reels of that matchup are in full color, not black and white.
I fixate on 2018 because after the New York Yankees agreed to acquire right-hander Jameson Taillon from the Pittsburgh Pirates in exchange for a middling package of four prospects on Sunday, that year has a special relevance for Bronx denizens sketching out their team's new-look rotation.
Let's say Luis Severino returns from his Tommy John surgery rehabilitation sometime in June, Corey Kluber's shoulder holds up enough that he holds down a rotation spot, Gerrit Cole keeps being Gerrit Cole, Taillon is a full go and, just for the fun of it, that New York's low-key minor league invite, righty Jhoulys Chacin, bounces back enough to win the No. 5 slot. The quintet would probably slot like this: Cole, Taillon, Kluber, Severino and Chacin.
In 2018, those five starters combined to go 83-38 (a .686 winning percentage) over 164 starts with a 3.16 ERA and 9.6 strikeouts per nine innings. They put up 94 quality starts. Together, they compiled 22.3 WAR, per baseball-reference.com. The MLB-leading WAR total for any rotation in 2018 was 22.4, by the Astros, but of course that total was bolstered by the presence of Cole.
