Here are some CERA/COPS numbers to chew on. Not big samples, obviously, but still.
Whitlock
Vazquez 62.2 IP 1.58 ERA .590 OPS
Plawecki 9.2 IP 4.66 ERA .909 OPS
Houck
Vazquez 49.1 IP 1.82 ERA .556 OPS
Plawecki 28 IP 4.82 ERA .679 OPS
Whitlock and Houck are pretty key guys for 2022.
Are we sure we don't want Vaz catching them?
