Arroyo brings as many questions to the offseason as choo. Maybe more. You sign him, and that gives you flexibility to move another pitcher. You don't you still have a solid albeit injury susceptible staff with chapman still closing.
I think the best route to go would first to look into moving position players for upgrades. Toronto has made no secrets about wanting a 2b and catcher. Maybe Phillips Frazier and hanigan there for Bautista. Make Bautista do a chooesque position change and put him at third. At that point you have to consider what else has happened. Can you move a starter bc you've resigned arroyo? Do you feel comfortable with chapman as a starter if no arroyo? Do you go FA? If they feel ok with chapman starting and have a closing option or bring arroyo back, then I'd look into a leake for Kendrick type of deal. If not maybe take a look at infante. After that fund platoon partners for the appropriate guys like mth suggested and I think we'd be set without giving up much pitching
