Last season, as most of Major League Baseball moved incontrovertibly towards a high velocity, strikeout-forward approach, the Cubs put together a soft-tossing rotation not at all focused on missing bats. Headlined by Kyle Hendricks and Zach Davies, perhaps the two preeminent control artists in the sport, the Cubs unique approach aimed–quite literally–to induce weak contact rather than avoid it. If success was a long shot, there was at least a strategy, even if their zag to the league’s zig was prompted by need.

Chicago’s pipeline of pitching talent had gone dry. The Jon Lester– Jake Arrieta-Hendricks triumvirate was the engine of the 2015-2017 peak Cubs. When they came to power in 2015, Cubs’ starters finished third overall in the Majors with a 3.36 ERA. They topped the sport by measure of ERA in 2016 with a 2.96 mark. By 2017, they had begun to slip, down to seventh overall with a 4.04 mark.

The magic was gone. As Arrieta’s superhuman years faded into the background, the Cubs let him walk in free agency. They made moves to replace him–trading for Yu Darvish, Cole Hamels, and Jose Quintana–some moves came before he left and some came after, but none could stand up to Arrieta in his short, but astronomical peak. Lester began to age, Darvish’s return to frontline status was a slow burn, and the Cubs settled into a groove of good, but unremarkable rotations, finishing 10th overall by ERA in 2018 and 2019.

David Ross’ squad sprinted to a sixth overall finish in 2020 by ERA as Darvish and Hendricks gave them a semblance of the staffs from the peak Cubs. Maybe their success emboldened the front office to give the offensive core one more opportunity to recapture the magic of the 2016 title run. But as we now know, the Cubs were at their best when driven by a top-notch rotation, and in 2021, they were stuck in the slow lane.

Only Hendricks and Davies made all 32 starts, but both posted the worst seasons of their careers as the Cubs lost 91 games. The rotation ranked 26th overall with a 5.27 team ERA, easily the worst performance since the Cubs took off in 2015. A power pitching game isn’t strictly necessary to field a competitive squad, but the Cubs do need something more.
