I do disagree with this.
Crawford isn’t a guy to headline your rotation, but innings eaters are more valuable than they get credit for. He was a 2.0 bWAR pitcher, which no one rejoices over, but it’s absolutely serviceable.
Part of his value comes from reduced emphasis on the rotation. If you look at the teams in the both LDS, you see some teams with rotations the kindest among us might call “questionable.” Detroit, for example, does have AL triple crown winner Tarik Skubal, but who else? The Mets have a rotation with people named Manaea, Quintana, Peterson, Severino, and ?? Megill, I guess? It’s a rotation that if someone said in March would be in the LDS, they’d be accused of taking LSD.
The Sox need a starter, but they need the bullpen more. Crawford isn’t exciting, but replacing him will just create issues that don’t need to be created…
