In addition to Tucker being a FA after this season, Suzuki and Happ are FA after 2026. Ideally, the Cubs top OF prospect after this off-season would get 150 PA in Chicago during the 2026 season.
At this point I wouldn't resign Happ for his current $20M salary. He's not a bad player if he was batting in the 7/8/9 spots and paid around $12M.
