Explore a potential Boston Red Sox trade idea that sends Rafael Devers to the Cardinals in a blockbuster MLB deal.

Spotrac puts his market value at 12 years, $539 million. ESPN's Jeff Passan also recently had Tucker in his rarefied air of players who could sign $500 million contracts. And if the Cubs are the ones making that happen, it's pretty unlikely they'll then turn around and trade for the roughly quarter of a billion dollars left on Devers' deal.
