It's funny; I looked at the first two items on this page without checking the date and was about to reply "Are you nuts? Nimmo's 2018 was better than Sanchez's 2017!" It's also funny that we're talking about most of the same players. All the same criticisms for Ramos still hold for example, but he can still hit when healthy. Alderson deserves some credit for hanging on to Nimmo when, this time a year ago, a lot of teams called about him. I do think Sanchez highlights the risk with catchers. A few dings and dents, and suddenly they aren't all that. Some absurdly bad luck (a .197 BABIP can't all be attributed to the shift) didn't help his cause, to be fair. But it justifies some degree of caution if a team is trying to extort us for a guy coming off a career-best .825 OPS.
