I'm not defending this team over the one it could have been with non-moves (that one is better), but Minor from Gray seems like a relatively modest trade down. They're both shelved at the moment, Minor has actually been healthier over the last 3 seasons. It's the offensive fire-power, especially of Winker/Castellanos together in the lineup, that they'll miss the most.
I do think this team would have to be keep intact, and get bunches of health/luck, to even sniff a wildcard spot. At least they'll be less pitiful against LHP with Pham, Solano and (fingers-crossed) Senzel as regulars.
