Is the way I see it, both will benefit with the change, Cubs need a closer and Schwarber bats is a plus everywhere, Betances has some things to work on his mechanics but has the goods to be a closer he only needs a pitching coach who can help him fix his delivery and stay consistent, Schwarber need to work in his swing, some time in the minors could help him big time, imagine a lineup of Judge, Bird, Sanchez and Schwarber ???? as a yankee fan I can dream about this. We might add Ellsbury and 2/3 of his salary to help them, he's still valuable in the field and was having a good season before his concussion.
I know is wishful thinking but you never now, Theo and Cashman always had a good working relationship, hope it happens
