I don't think we are speaking the same language here. Teams emerge from "rebuilds" by having a core group of players who you build around or a couple home grown or cheaply acquired players who turn into superstars.
The sox farm is world's better than it was in 2019, but the only two guys who really profile as All-Star level players are Casas and Mayer, and some of the bloom has fallen off Casas' rose lately. Mayer isnt gonna be ready until 2024 at the earliest. Bello and Mata have great ceilings, but they also could end up as multi inning relievers if they struggle with command (like Bello is doing now). There is much to be decided and it will be decided in 2023, which is why you aren't able to pull yourself out of this nosedive in one season.
Right now, the Yanks are lapping you and the rest of the AL is pulling away. 2022 looks like a bust right now. After 2022, this is your returning team
C- Wong
1B- Casas
2B- Downs
SS- Story
3B- Devers
LF- Verdugo
CF- Duran
RF- ??
DH- Dalbec
That lineup has holes inside of holes. You aren't fixing that internally and with the FA market that is out there, you aren't fixing it externally. While you may have better depth than before, you don't have the depth to acquire talent in the offseason when it comes at a premium. Let's look at rotation
SP1- Sale- never stays healthy, breaks bones laughing
SP2- Pivetta- really a SP5, but this is what you got
SP3- Bello- high ceiling, looks like cannon fodder right now
SP4- Crawford- low ceiling, probably better off as a long reliever
SP5- Winckowski- sucks big time
CL- Houck- solid stuff, very inconsistent
SU- Whitlock- top notch, can give innings, injury risk
In the rotation, you could need as many as 4 starters to be relevant again.
All I am saying is the sox system cannot kick start this team on it's own as there are too many holes. It still doesn't have enough impactful guys and doesn't have the depth to start the upswing phase of a rebuild. You will need a few years to kick start it and you can shorten that window if you deal off some expiring contract players for some prospects of value
