Yes at the start of the offseason most every competitor has a number of holes to fill, that's how offseasons work when a big chunk of the player pool is no longer attached to a team. The Dodgers rotation at the moment needs multiple guys to come back from TJS real strong real fast, they have no DH and are apparently betting real heavily on Heyward being a starting caliber corner OF. The Padres rotation is Musgrove(coming off shoulder injury), Darvish, and a pile of sorrow. Last year's division winners the Brewers have Jake Bauers and Tyrone Taylor as their 1B/DH and Adrian Houser as their 3rd best SP.
At the root of this anti-logic is the sentiment that the worst thing you could possibly do is spend resources a year too early, I get it but it just isn't a significant risk. The Cubs were garden-variety variance from a playoff berth, will either have leg up in keeping Soto or recoup some cost through a pick, and he is a very snug roster fit. Waiting until you have all the other pieces in place before considering a star player(and I mean a real star level impact, not Pete Alonso/Jordan Montgomery level guys) who isn't a perfect contract fit is a great way to run into a situation where you don't have the ability to acquire one because they aren't available or not in a spot where you need to improve.
