When you take a look at the Cubs rotation for 2020, a lot of weight is being put on Yu Darvish to perform the way he did in the back half of the 2019 season.
Yu Darvish was one of the first to accuse the Astros of cheating and signaling their batters of up coming pitches. A lot of people thought it was just sour grapes from Yu for his bad performance against the Astros. It a shame that that might of messed with his head for a while, but like you said he seems to have his head on straight and had a great 2nd half last season. Looking for a great year from Yu this year with him becoming the Ace of the staff that the Cubs organization had expected him to become. Nice Column!
