Add Manny, Pederson, and Eloy to what they already have and that is suddenly pretty good. The bullpen is much improved as well. The rotation is iffy, but adding a vet like Gonzalez would be nice.
Rodon/Lopez/Gonzalez/Nova/Giolito isn't great, but it's not awful either. That group should at least give them a chance to compete in a poor division next year. Then Kopech and Cease can replace Gonzalez and Nova in 2020 and maybe a guy like Dunning will be ready by then too.
