The Chicago White Sox are pretty loaded at the catcher position. They have Yasmani Grandal and James McCann. Seby Zavala and Yemin Mercedes are also in the organization to play if needed which might make Zack Collins expendable. He would be a good piece for the Cubs to go after in order to send Schwarber to the White Sox. There is a need for each team getting a new player at a specific position
We don’t know if the Cubs are going to move on from Willson Contreras for the same reasons they would move on from Schwarber. That will mean they need to fill a whole behind the plate and Collins might be that guy. He has been a highly-touted prospect that just needs to get some consistent opportunity. He could form a nice duo with Victor Caratini if they got rid of Contreras.
Dane Dunning is a starting pitcher who the Cubs would be smart to add if they let the White Sox have Schwarber. The Cubs have been so bad at developing pitching during the Theo Epstein era so adding a stud like Dunning might be nice for them as they try to retool. These are good players but if the White Sox are truly entering “win now” mode, this might be something worth considering.
