What are the most infamous trades in Miami Marlins history? Miguel Cabrera could have been forever known as a Marlin, but was traded for prospects who didn't pan out at all in Miami. In 2012, the Marlins shocked the world by trading "everyone" to the Blue Jays in a salary dump. Giancarlo Stanton signed a huge extension, and then was immediately traded under a new owner. The Marlins ownership has never shown loyalty to players or a dedication to spend.
