There is a way we can keep both... "but obviously it will be difficult," said Sam. So maybe they went out and hired Bloom as the best man to make it happen and overcome those difficulties.
Devers and Bogaerts were better all-around bats last year, but Betts and JD are the two most important men in the batting order -- it was just two seasons ago they were the top two hitters in the AL. If I were building or rebuilding a team, I'd make every effort to keep both, along with Bogie and Rafie, and make every other player in the organization available.
But if I had to guess -- based entirely on my subjective reality as a lifelong member in good sitting of Red Sox Nation, plus the history of how Tampa views the DH as an interchangeable slot in the lineup -- I'd say JD would get dealt. Mookie is the face of the franchise, while DH for Bloom and his past company is a flexible position of options (seven Rays DHed 13 or more games in 2019, with Meadows, their All-Star outfielder, getting the most starts at only 44).
