In July 2017, the Cubs traded two top prospects (and two others) to the White Sox for Jose Quintana.
It was hoped that Quintana would help bring another World Series title to the North Side.
Obviously, that hasn’t happened. Now, that isn’t Quintana’s fault. He’s put together a decent season and a half in blue pinstripes, although his numbers weren’t quite as good as his time on the South Side. He was worth 1.3 bWAR in 2017 for the Cubs and 2.2 bWAR in 2018. This is a marked drop from his White Sox performance, where he put up four full seasons with better bWAR than his 2018 season with the Cubs.
