I wonder if the amount of money Miami has to spend on what they have coming back from the Dodgers for a prospect and Euvaldi fo Hanram is a tip off to what might have screwed a Boston deal.
Clearly, if the Sox were going to send Crawford to Miami, the Marlins were likely going to want Boston to pay some part of Crawford's ridiculous contract. Maybe once the Marlins scouted Crawford, the money they were demanding from Boston just got to be more than Boston could handle or at least would handle.
So at least based on what the Marliins actually did with LA, I am inclined to think that the expectation would have been for Boston to pay for Hanram and pay for a big chunk of Crawford. The money maybe just got to be more than the Sox wanted to deal with. Carl is way overpaid under the best of circumstances and these are not the best of circumstances.
