Sox need a couple big moves that could easily propel them into being a WS contender. Yes, this assumes some forward progress and growth by guys already on the roster, but that may be reasonable with the likes of Casas, Duran, Yoshida, Rafeala etc etc.
They need two big-time starting pitchers, or at least 1 ace and a good mid-rotation starter.
They need a big RHB.
They can get 2/3 of these easily in free agency if they are willing to spend. With the firing of Bloom we can be optimistic here but it's certainly uncertain if that's the direction they take.
The big RHB is not as clear. There's nothing in FA, and one could argue if Rafeala can hit, Story is finally healthy and they resign Duval that they may be ok there. But they can't bank on that happening. Still, if all they did was resign Duval but then went out and got two legit pitchers to add to the rotation E.G. SNell + Yama I would be happy and very optimistic for the 2024 season.
