Steve Cohen
The New York Mets operate under the shadow of their city rivals but Cohen isn’t making their lives easier. The franchise owner promised World Series titles when he bought the team but this may be far away. Mets fans greeted him with excitement because they thought a massive change was around the corner (via New York Post).

When things went wrong, Cohen preached patience before he had a public temper tantrum. Furthermore, the team is dysfunctional behind the scenes with player petulance rising to the fore. It didn’t help that police arrested the assistant GM for sexual harassment. Maybe buying the Mets was Cohen’s biggest mistake.
