In case you want to start dreaming up and discussing ways for the 2021 Brewers roster to be improved here is a thread to discuss players that will be free agents this winter. List to review the upcoming free agent class: 2021 Free Agent Tracker (FanGraphs) FanGraphs also did an article explaining some details of their Free Agent Tracker (Link). Additional players will be added to this pool as non-tenders occur, and teams or players decline/buyout option years on contracts. As mentioned in the second link, some likely examples of team options being declined include Chris Archer, Jake Arrieta, Brett Gardner, Corey Kluber, and Carlos Santana while both Nick Castellanos and J.D. Martinez could opt out of their current deals. If those things occur they would obviously become free agents.
