One never knows about these things, particularly given the vast financial uncertainty facing all clubs for next season. But the Cubs do seem to clearly see this next season as a transition so I expect to see some meaningful changes, assuming the opportunities are there.
I am looking forward to someone doing an analysis of the likely status of Cub salaries next year, given that they will presumably reducing the total due to the loss of Quintana ($10.5m this season), Chatwood ($13m), Lester ($20m, with $10m buyout for '21).
I am guessing that the Cubs will try hard to trade Schwarber ($7m) and very possibly Bryant ($18.6m) as well, and that there will be other lesser salaries gone such as Almora gone too. I'm guessing they will not try to trade Baez, although if they cannot reach a long term deal, maybe he'll be available as well. Same with Contreras?
