I think it's an ok group of 4 pitchers. I'm not sure what Dobbins is just yet. Possibly just a backend guy. Fitts still needs to come back from injury before we can really count on him.
Crochet is a certified #1.
Bello can be a #3.
Guys projected to appear in 2026 per Sox Prospects: Perales, Early, Mullins, Monegro (Early probably has the best chance to start)
Guys projected to appear in 2027 per Sox Prospects: Tolle, Valera, Clarke, Paez (this group is far more interesting than the '26 group)
The rotation in 2028 (not THAT far away) could be:
Crochet
Bello
Valera
Clarke
Early
