In an effort to avoid a 3000 word screed ramble post, here's some questions and my assumed answer that I think clarifies what the approach will be and what decisions are the tipping points. I also think it's instructive to again ask what it means to 'sell'.
1. Does Jed have enough job security to trade from the multi-year core he has created(Swanson, Hoerner, Seiya, Happ, "Taillon") and make 2024 worse than 2023 and increase their timeline to a playoff berth? I'd say no.
2. Since even the most optimistic of us did not think a playoff berth was probable, it's most useful to think in terms of 2024 expectations. How has the outlook for 2024 changed compared to the start of the season? I'd say it's muddled, there have been clear improvements vs. middle of the road expectations(Steele, Swanson, Morel, Alzolay), clear disappointments(Taillon, Seiya, Mancini, Mervis, Stroman shooting the moon and guaranteeing opt-out), and some shades of gray(Amaya, Madrigal, Wesneski). I would summarize this that if they thought the current roster could continue progressing to be a clear playoff team in 2024 that is still on the table, but not as clear cut as it could have been.
3. What players have trade value and can't reasonably expect to contribute to a 2024 contender? Fulmer, maybe Hendricks? Mayyyyybe Mancini if he picks up the pace for a few weeks?
4. What players are borderline to contribute to a 2024 contender that have trade value and might be traded? Stroman is the headliner, and by extension Bellinger would too even if I don't think he's going anywhere. Smyly and Madrigal make sense depending on other roster decisions and what they could bring in return. Hendricks could also fit here too(I think by production it's possible he's on a 2024 contender but roster considerations make it very unlikely)
