But there's nothing to suggest Caratini is a good defensive catcher, right? He was a negative value defensively until 2019, and even then it's not overly impressive. I get that he's already on the roster, but any sort of platoon with Caratini getting 80+ starts isn't one centered around defense. Depending on which framing metric you want to trust, Caratini was between 5 and 15 runs better than Contreras as a framer last year. Statcorner: Caratini +9, Contreras +4 Fangraphs: Caratini +2, Contreras -9 Baseball Prospectus: Caratini +5, Contreras -10 EDIT: The BP number includes throwing and blocking, on framing alone it's Caratini +3, Contreras -9 I wasn't saying they were equal, I know Contreras is bad, but I don't think that gap really comes that close to making up the offensive gap. I definitely see the argument, I'm just betting on Contreras as an upper .800s OPS guy, and someone who can be taught to cut down on the throwing errors, taught to be more focused behind the plate, etc.
