If Suzuki is willing to platoon with Busch at 1B and play DH, then Suzuki makes sense as a Cub. But if that role is a problem for him, then a trade makes a lot of sense.
With the possibility Tucker walks after 2025 and Happ/Suzuki are FA's after 2026 the Cubs need to develop Caissie, Alacantara or Canario in Chicago during the coming season. IMO the Cubs FO needs to have some confidence one of those 3 can be an everyday outfielder in 2026.
I understand the appreciation for guys like Suzuki and Happ- but the reality is they are .260-.280 hitters who'll knock 20-25 HR's. Nice production for the corner OF spots, but just enough to be a .500 team the last 2 years with the surrounding roster. Maybe Tucker can be the difference maker that Bellinger wasn't, but it probably needs to come from multiple spots: DH, 1B, 3B or SS. In the case of SS, Swanson needs to have a break-out year in 2025.
