That deal isn’t nearly as one sided as you suggest. Bell has negative value with that salary and his ground ball rate. He sucks. I would rather play Mervis at 1st. Sure, Cabrera is decent, but he isn’t that valuable either. Maybe Killian doesn’t get the deal done with Mervis, but I wouldn’t give much more than him. Maybe Thompson. Marlins cut payroll. That is their motive. Cubs get Cabrera. That is their motive. As for Bell and Mervis, I think the Marlins get the better option and definitely get the better value.
