Not to be argumentative, genuinely curious - why do you say 2024-27 as opposed to something like 2026-29?
Of our top 10 prospects, the only ones expected to even be up to start the 2024 season (per Sox Prospects, and I think of them as a legitimate source) are Casas, Rafaela, Mata and Walter, the last two of whom they project on their own scale as "bench / utility" players, which for pitchers I'll equate as 5th starters / swingmen.
Based on what we have under contract / control for 2024 (not to mention 2023) and our present spending models, you're looking at something like C - McGuire, 1b - Casas, 2b - Story, 3b - I'll guess "Josh Donaldson" since that seems about our spending pattern; SS - I'll guess "Elvis Andrus"; LF - Yoshida, CF - Rafaela(?), RF - Verdugo; DH - I'll guess we "re-sign" Turner with another $15m next year or some such. SP - Whitlock, Bello, Houck, lets guess Mata (or "2024 Michael Wacha) and a 35 year old Chris Sale. That doesn't look like an "open window" kind of starting roster.
To be clear, I think some of the prospects will be really good, some will be "capable players" and some will suck. Kind of how it worked out with Betts, Bogaerts, Benintendi, Devers, Bradley Jr, Doubront, Middlebrooks, Iglesias, and whomever else I'm missing since I just went off the top of my head. Keeping in mind the 2018 team also had huge free agent expenditures (at the time) at DH, SP1 and massive trade acquisitions where we moved high level prospects at SP2 and Closer. I've seen nothing that makes me confident Bloom will sign those kind of deals (Martinez and Price) nor make those kinds of trades (Sale and Kimbrel), and certainly not anytime before the off-season leading into the 2025 campaign.
Could 75% of the prospects hit and THEN Bloom decides to swing massive trades and sign elite talent - in the off-season before 2024 or 2025 - I suppose, but that's a TON that has to go right and very little margin for error.
