Here's a BTV trade that works 3 way with the Cleveland Guardians.
Disclaimer: I know this is a long shot, and does not fully grasp team needs and evaluations, but it's for fun and conversation.
Tigers get: Travis Bazzana/Connelly Early/Michael Kennedy
Guardians get: Jarren Duran/David Sandlin
Red Sox get: Tarik Skubal/Khal Stephen/Jacob Cozart
Why the Tigers do it. They can't resign Skubal, so they go out and get value for him now. They get a controllable pitcher with 6 years of team control, and a top infield prospect in Travis Bazzana who fills a need on their roster, and another young arm in Kennedy.
Why the Guardians do it. They reportedly have liked Duran and need both help in the outfield and the bullpen, Sandlin is a high minors prospect who many think is best suited for the bullpen who could probably accelerate his path to the majors by committing to the bullpen.
Why the Red Sox do it: Do I really need to explain????
