Not now. He's arguably their best player, and they already dealt their former best player this offseason.
But in notin's defense, a few months back I also suggested a similar deal as the best way to add legitimate pitching prospects; after all, one year of Betts only got us LA's most expendable position prospects. Of course, my only contingency in ever trading Devers is if that meant that Betts had agreed to a lifetime extension. Even then, say we acquired the Braves' top three prospects -- they're all just that: prospects. Devers led the majors in extra base hits at age 22.
Will Rafie continue to star for the next half decade in Boston like Mookie did through age 26? Hope so, but that's a lofty expectation, since Betts's career WAR in RF through age 26 is the greatest in baseball history.
I agree that Dalbec should be swapped for a young arm with potential. He's blocked at third, has never profiled as a .300 hitter like Devers, and is also blocked at first down the road by Casas, the top power prospect in the Sox' system.
