It's a controversial topic, and in my opinion often misused. Looking at just team CERA is not an accurate methodology. One major variable is the unbalanced innings caught from one pitcher to the next, so I have done studies of CERA and OPS Against pitcher by pitcher with a stronger emphasis placed on examples that have larger and more balanced sample sizes.
I've done this for many years, and will for this year, when I have time. The results show Wong has been pretty good (vs Narvaez in 2025 and McGuire/Jansen in 2024 and others before that.) This is not to say Narvaez or others sucked, but Wong did get better results with more pitchers.
