As good as Cody Bellinger might be, I think signing him this offseason would be a huge mistake. He made the least hard contact of his career and all of his peripherals suggest he was pretty lucky. He also still chases a ton despite reducing his whiff rate.
I think the Cubs will be looking at moving one of their other OFers though. Happ/Suzuki have 3 years at ~20m per, and they also have Crowe-Armstrong, Canario, Tauchman (4th OF), and Morel (UTIL), with Alcantara and Caissie in the upper minors. Jays have been interested in both Happ and Suzuki in the past.
They need a 3B, 1B, and pitching. Horwitz is an option, don’t think the Jays are interested in moving OMart/Barger unless it’s a more impactful add, and we have quite a few pitching options we could deal from. I also think the Cubs will be in the market for Chappy and Hicks (whether as a starter or reliever).
