Chicago Cubs: B+

Preliminary Grade (Feb. 16): B+

Key moves since preliminary grade: None

The only real quibble is the extent to which the defending champions have taken on health risks (pitchers Brett Anderson, Wade Davis and Koji Uehara and outfielder Jon Jay), and that they didn’t aim higher in replacing centerfielder Dexter Fowler.
