The biggest piece the Cubs traded for last summer was a closer by the name of Aroldis Chapman. While he tired down the stretch, he was one of the biggest reasons the team was able to succeed in October. He is gone, as are other arms, but the front office tried to re-tool the bullpen, so there would be no drop off heading into 2017.
As Spring Training begins, the questions too begin about the changes in the bullpen and whether or not they will keep Chicago from winning back-to-back World Series for the second time in franchise history.
