It’s funny how “offseason champions” work. We saw it last year with the Padres, as their new GM acquired new shiny toys that ended up being sorta polished toys bought at Goodwill. That team was flawed from the get-go, and since then A.J. Preller has worked some magic, including today’s trade that sent two meh pitchers to Miami for a great reliever and their third-best prospect (and Jarred Cosart, who you could argue is as good as Andrew Cashner or Colin Rea).
This year, the Diamondbacks made all the splashes in the offseason.
