Here is the final report on Vaz, as compared to other Sox catchers and how well our pitchers did with him or others catching them.
Call it CERA. Call it staff-handling. Call it whatever you want, but almost all of these numbers point in one direction: other catchers got more from our pitchers than Vaz did. This doesn't mean the others were better, overall, or that Vaz did not deserve to start or that he sucked as a catcher. It just shows one aspect of a catchers job and how Vaz compares to other on the Sox.
I listed all Sox catchers who had sample sizes larger than 40 IP. One can argue 40-80 or 100 IP sample sizes are too small, and it's a good point, but when they almost all point in the same direction, and the samples with 100+ IP each all show the same thing, I think the numbers speak for themselves.

Overall, Vaz did about the same with the second tier SP'ers and the top RP'ers, but much worse with the top 6 SP'ers from 2014-2022.
Take it for what it is.
I still liked Vaz as a catcher, for us, but I think these numbers take away some of the shine.
