FWIW, I'm not voting because I don't see an answer that really encapsulates this, but I'll try my best to explain it.
I understand and accept that you're not going to have a sustainable product without a sustainable farm system and a good core. People always point to 2013 and 2021, but those two really weren't at all alike. 2013 had two major bats in the middle of their line up that were an established star and an established once in our lifetime player, both under contract for multiple seasons. It had an ace under team control at the front of it's rotation (Lester), what looked like a very solid second starter under control for many years whom could deliver ace-like performance on any given night (Buchholz), what looked like a decent young pitcher coming into his own (Doubront) and they in may ways got very lucky with Lackey.
They had one more year of a very good table setting leadoff hitter whom everyone knew was headed toward free agency.
They also had a very good farm system with multiple high end prospects on the cusp of the big leagues or just getting there in Iglesias (obv traded for Peavy), Middlebrooks, Bradley Jr, Bogaerts and Betts. They added to that team without making big deals, but they did have veterans whom would be around for a while and weren't just one year "hope for the best" options (though they did get the best out of those guys in that one wonderful season).
2021 had Bogaerts under control for one more season, JDM under control for one more season and basically nothing.
Anyway, what I want the Sox to do is:
Let the kids play. Not exactly tanking, but let them take their lumps in a season where they were never going to be playoff contenders anyway unless everything went exactly right. I really and truly enjoy watching games started by Whitlock, Bello and Houck. I don't personally think Crawford can cut it as a starter, but I'm more than fine throwing him out there every 5th day to see if he can be.
Give as many at bats to Casas, Duran, Valdez and Wong as possible. I think every plate appearance by Hernandez, Refsnyder, Arroyo, Tapia and Reyes is a lost opportunity.
I'm generally speaking "fine" with the one year deals for pieces like Duvall, Turner, Kluber, etc (or Drew in 2013) if that is the route one prefers. I would personally rather go after guys whom could provide a bit more stability (case in point this year I wanted Bassitt, Wacha, Tallion and Eovaldi, in that order) but if someone really prefers the one year deal, fine. I understand that those give more flexibility, so I'm not really disagreeing if someone really prefers that.
However, with that one year deal if you're not in playoff position (better than 50/50 odds of making it around the deadline) sell off literally every single player whom isn't under control for the next season. Maybe you get lucky and land Ben Brown. More likely you land Connor Seabold. But sell off literally everything that won't be around for multiple years and start again the next year and give more at bats to younger players.
I don't mind watching a young team struggle because there is at least something being built there. Watching a team with all these one year deals struggle is an exercise in futility.
Oh, and if somehow the team playing all youth over-achieves and is in playoff position or CLOSE to it, be a buyer and let them experience a really playoff chase where you actually commit to the team. Do not be a "half in / half out" team, I think that is literally the worst spot a team with the financial resources of the Sox can be.
