I see it differently. However, because the Sox are playing the toughest schedule in all of MLB, I can't argue too much with your last paragraph.
To repeat what I've already said, this Sox pitching staff has the same team ERA, 3.74, and the same ranking, 8th, as the 2018 Sox. The hitting isn't nearly as good as 2018, but the defense is better.
And this. Breslow last offseason signed Bregman, Crochet, Chapman, Narvaez, and Buehler. Plus this season the Sox brought up Anthony, Mayer, and Campbell. Story is worlds better than he has been for the Sox. Rafaela is too. Narvaez is a huge improvement at catcher. Giolito is finally paying off, and Bello seems to be finding himself. Granted, Buehler stinks, but in July he pitched 22.2 innings in 4 games with an ERA of 3.57. Two of those games were quality starts.
Based on those observations, I think the 2025 Sox have been a transitional team and are now hitting their stride. I suspect the departure of Devers helped.
The glass is not half empty.
