The St. Louis Cardinals have dragged their feet on this current rebuild for some time, and it only finally started getting off the ground once Sonny Gray was dealt to the Boston Red Sox for Brandon Clarke and Richard Fitts.
That still leaves notable figureheads like Nolan Arenado and Willson Contreras as valuable trade candidates, not to mention a number of younger contributors who could be worth quite a bit on the open market. Even if the Cardinals don't want to trade everyone from their core in one offseason, it's expected that they'll blow up the foundation in order to start from scratch.
