Dodgers: Which free agents should the Dodgers bring back?

Russell Martin’s mentorship still has value
Russell Martin returned to the Dodgers in 2019 and it was more than just a heartwarming homecoming story. Russell Martin provided great mentorship to Austin Barnes and Will Smith that Dave Roberts talked about multiple times throughout the season. Martin also ranked well defensively according to StatCorner’s catcher report.
Offensively, Russell Martin still has some pop left in his bat and can get on base at a decent rate for a backup catcher. Will Smith will be the Dodgers’ primary catcher in 2020 but he is still young and if the Dodgers feel that Austin Barnes is not going to provide good veteran leadership, then bringing Martin back would be a wise decision. If Barnes is ready to be that veteran backup catcher, then Russell Martin shouldn’t be brought back.
