I never mentioned Devers in my post, but glad to expand.
No matter how it's-still-early, the '23 Red Sox have just one above-average player on the diamond. That explains more than anything why they suck.
Besides Raffy, not one position player has played an entire major league season at their starting positions. Verdugo is the closest, as mainly the rightfielder for two months of 2020.
The offense will improve, because Boston won't keep starting five guys batting below .200. The pitching will improve, because young arms will soon replace dead old arms that are serving up BP.
But the real problem that needs to be rectified is the DEFENSE. The Sox will not compete or even be respectable until they fill C-SS-2B-CF with solid, full-time big leaguers who actually play those positions. It may take time to find different players, and it may take different GM/CBO/Manager/Coaches to find them...
And don't fall for waiting for the wounded to heal; recruiting injury-prone players is part of the problem. New management will start with targeting and paying for dependable athletes in their primes.
