Really, any improvement has to come from:
Healthy contract year Moncada
Healthy, motivated Eloy
Head-on-his shoulders Colas not in Pedro's doghouse
Sosa/Rodriguez emerging at second base or Lopez having a .347 BAPIP that he had 2 years ago instead of the .250 range that he has had the rest of his career
Benintendi playing like he did prior to be a White Sox
Andrew Vaughn developing
Prayers in the bullpen
Korey Lee hitting better than Zach Collins
Colson Montgomery being the guy we hope he can be
Kopech's arm strength holding
Mena and Nastrini reaching the major league level and having absolutely no growing pains
Edit, forgot two:
Hope Mike Soroka regains his 2019 form, like Yoan!
Bank on KBO form Erick Fedde (I'm actually super intrigued by this)
