I'd ship those 3 out for Stanton before the Marlins could hang up the phone. There are different kinds of prospects, I'd put both Rosario and Nimmo in the "could be huge studs but could be total flame-out duds" category. neither of them has the "high floor" of say Conforto that makes me less want to trade a guy. Meanwhile, gavin cecchini, who never really fell behind in the "who will be ready first" contest has probably pulled back ahead of Rosario this year in the "more likely to be the SS of the future" and "more likely to have a solid career" categories. Trading should in part always be about absolute value (which is why i don't like Meisner for 20 innings of Clippard), but when you have multiple guys of similiar value which one you prefer deal depends on other factors, i would think Rosario has become more tradeable this year (with Cecchini's performance)and Nimmo less so (with Lagares floundering, Cuddyer sucking/hurt). Gomez looks like fool's gold. his range has dropped off and his basestealing disappeared too this year (he was hurt though i think?)
