In terms of overall depth in the minors, the Cubs have a lot of right-handed relievers with potential. The slew of arms also includes several with whom many fans are already familiar and who have just been waiting to get a chance. For instance, Dakota Mekkes and Michael Rucker spent all last summer in South Bend without getting a call to Chicago.
Considering the current financial state, the Cubs may not have many choices when it comes to bringing up relievers the next couple of years. Being in a win-now mode all the time means developing long-term assets in Chicago is not a priority, which is why James Norwood and Dillon Maples kept getting chances with very limited patience.
