I really don't want this offseason to be focused on anything besides sorting out their longterm rotation options and accumulating potential impact talent with trades of Burnes, Adames, and even Devin Williams. Use 2024 as a legit retooling/rebuild season and open up as many MLB opportunities for their young players to sort things out in the OF and at corner IF positions. If Black can even be a hack defensively at 3rd, he should be their Opening Day 3B. If Black fails there defensively and winds up as a DH candidate, there are other 3B prospects recently drafted who may be fast risers through the system, too. Wilken should be viewed as a legit 1B option with his power, probably not ready right away next season but who knows? If none of the young OFs are dealt as part of any trades, Wiemer should start 2024 in AAA with Mitchell and Frelick the other OF starters opposite Yelich - then if Chourio hits the ground running in AAA he's up and Yelich becomes your fulltime DH for the rest of his contract. I think a healthy Mitchell over the course of a full MLB season will give you 25HR.
Once (if) Wiemer figures things out at the plate he's your 4th OF with pop and premium OF defense. Plug Turang in at SS and let him mature at that spot on the cheap for a few seasons until sorting out if one of the other Brewers' SS working through the minors pushes him out of the organization or if that's a position to target via trade when the team is once again ready to contend.
Yes, the Brewers need more pop in their lineup - but they've got to give homegrown youngsters MLB time to develop and see if they can find that with who they've already got in house. For a bridge, I like the idea of trying to keep Santana around, assuming (and hoping) guys like Canha and Tellez are gone. Also, find a 2B with at least a little pop in free agency/trade (Jorge Polanco from the Twins on a 2-3 yr deal sounds pretty good and likely pretty affordable).
Specific to Devin W., they could get a haul for him with a trade this offseason but the Brewers may want to go into 2024 with him as their established closer - and if they aren't anywhere near contention they'd be able to get a haul for him at the July deadline, too.
