I don't dismiss anyone at all. That would be conceit at it's worst, not my proverbial bag.
The Orioles are a good example though of why I think the Sox should sell (if possible) before the season if they enter with the rotation they have.
To be clear, I think Bello is presently what I'll call an SP2 (just for ease of typing), Crawford is SP4/5 and Pivetta is SP4/5. Could Bello get better - of course. If we're going to assume Bello will get better, we have to assume the same for Bradish. If we assume Crawford can become an SP3, we have to assume the same of Kramer since they're both going into their age 28 season. The Red Sox have no Grasyon Rodriguez but I think we have to assume he is going to live up to his prospect pedigree if we're going to assume improvement from pitchers that were lesser prospects. If one wants to assume Winckowski could become a decent starter based on his relief appearances, wouldn't it be incredibly unfair not to assume the same of the younger and more highly regarded DL Hall.
I won't bother to go through the line up because the two aren't close, but suffice it to say just as an example that whatever improvement we project for Casas (which is fair) we have to assume the same for Gunnar Henderson.
The delta between the Sox and the playoff contending teams (Baltimore, Toronto, Houston, Texas, Seattle and Tampa) was pretty extreme, and the summation of moves the Sox have made to improve on that delta is getting a better 2b (which is great, but we're not exactly talking Grissom being worth 10 wins - the difference between the Sox and Seattle, who missed the playoffs).
Even when you look at the team the Sox were "closest" too (New York) they added Soto and Verdugo. If we're going to assume the Sox won't be ravaged by injuries, we have to assume the same for the Yanks (meaning they get back Rodon and Cortes). If we assume Crawford improves, we have to assume the same for Clark Schmidt.
Even if the players in question for the Sox make improvements (entirely possible) we need to assume the same for similar players (with better pedigree) on other teams or we're not being consistent.
Which is why I think the Sox should sell players that won't be here in 2025 and beyond now (Jansen, Martin, Pivetta if not extended), etc.
At a certain level, I'd even get the idea of going in with a rotation of Bello, Gio, Crawford, Houck, Winckowski and Whitlock if for no other reason than to see if in 2025 you need to get 3 additions to the rotation (or 4...or 1...). But you should still sell off those older assets rather than waste them (the way Duvall, Turner and Paxton were wasted last year, for instance).
