The Boston Red Sox and Pittsburgh Pirates could come to terms on a blockbuster trade under one major condition.

The Red Sox could move forward with Arenado at third, Devers as their DH and Casas at first base for the three years remaining on Arenado’s contract without disrupting anything related to the development of Campbell, Marcelo Mayer or Roman Anthony. That’s no small thing in the attempt to get more functional.

"While signing free agent Alex Bregman remains an option, the Red Sox reportedly prefer to take on Arenado's remaining contract rather than dish out the big money that Bregman and agent Scott Boras are seeking on the open market," Geagan wrote.
