to actually say this, you have to be: a) a complete skeptic of the effect pitch framing can have b) totally unaware at the discrepancy which exists between the two players

I'm skeptical of how much control catchers have over that effect, and by extension, how much benefit getting a player from another team with quality framing numbers would offer. I'm skeptical that it's not a skill like bat speed, where small losses due to age have large negative effects. And I'm skeptical that given their ages, that Castillo and Martin's offensive production won't converge. That said, I'd still bet that Martin is better than Castillo for the next year or two, but I'm not sure how much. I'm not SURE how much either, but I think it will be quite a bit. Welington's not very good.
