Wrong. The Marlins HAD to sell for pennies on the dollar because they're deep in debt and absolutely cannot afford Stanton's contract when the dollars start really getting up there. They needed a trade partner who would eat pretty much the whole contract. Logic dictates you don't get blue chips in return for hefty salary dumps, and this was the salary dump of all time. And you don't know what the Dodgers did or didn't offer, and AFAIK Stanton didn't say whether he would block the Dodgers or not, did he?
Marlins were playing with no cards here, Stanton had them over a barrel and their own financial ineptitude had them over a barrel as well.
