so, i'm not entirely sure my math is correct here. but bear me out. nido has a ~.550 OPS and ramos has a 0.800 OPS. ramos has a .363 OBP and .438 SLG. nido has a .232 OBP and a .317 SLG. in the same 5 plate appearances, ramos reaches base 1.82 times, whereas nido reaches 1.16 times. in the same 4 at bats, ramos gains 1.74 bases, whereas nido gains 1.27. the difference between these players, offensively, over the course of a game is... half a base or so...? maybe a full base if you think you can add the partial contribution of OBP to the partial contribution of SLG. what i'm saying is, that whatever offensive contribution ramos has over nido, in the course of a single game, is not at all overweighing the 0.75 runs in cERA difference. and if that cERA effect is greater for syndergaard, for whatever reasons, then the offset is even farther. basically, it's not at all unreasonable to think that syndergaard, and the mets, might be better off with nido catching.
