Fred Wilpon
The Wilpons ran the New York Mets into the ground with a bunch of garbage decisions. They made terrible draft picks that failed to help the team and turn them into a contender. Meanwhile, they couldn’t appoint a decent manager or coach if it meant saving their lives. It takes an education to become this inept but they turned it into an art form.

Then there was Wilpon’s business partner Bernie Madoff. The Ponzi scheme leader received a 150-year prison sentence after he defrauded many people. It’s safe to say that Wilpon is a shady individual in sports as well as his regular business life. Mets fans can’t even say that he’s a winner because it’s not true (via NPR).
