I'm going to trot these numbers out again:
2021 catcher splits
Houck
Vazquez 38.1 IP 2.11 ERA .536 OPS
Plawecki 30.2 IP 5.28 ERA .693 OPS
Whitlock
Vazquez 63.2 IP 1.55 ERA .583 OPS
Plawecki 9.2 IP 4.66 ERA .909 OPS
Small samples, of course, but you have to consider the possibility that Vaz did amazingly well with these two, who may be the most valuable pitchers on the staff considering their ages and years of control.
I would be hesitant to move Vaz and his not exorbitant $7 million salary based on those numbers alone.
