If the Cubs traded Taillon for Detmers before the season straight up in an alternate universe, one of their trade targets, they’d theoretically be 42-33.
Trading for a starting pitcher might not make them a top 10 pitching staff but run prevention from our gold glove defense only works if you can limit home runs. Cubs are ranked dead last in home runs allowed at 1.5 game, they’re 27th in fWAR and a modest 17th in ERA. So top 10 in ERA is certainly achievable and more economical when you factor in the amount of farm capital it’d take to land Alvarez over the available pitchers.
Ben Brown in 26 and Cade Horton in 25 both have xERAs between 1.2-1,3 runs higher than their actual ERAs. No matter how frustrating the offense can be at times it can’t be overstated just how much those same streaky hitters mask the deficiencies of our pitching staff playing defense.
