I'm not sure this makes them any better than they ended 2023. Urshela is a bit of a 3B offensive upgrade, but a defensive downgrade. Naylor should be a significant upgrade at 1B, but realistically, the Cubs are getting a significant offensive down grade in CF. So maybe the offense is very slightly better. I'm not sure that Bieber is even an upgrade over 2023 Stroman. This is ,more or less, bring back the same talent level as the 2023 Cubs, but with pieces swapped.
