18. Art Modell – Cleveland Browns
LeBron James is not the most hated man in Cleveland. No, that dubious honor goes to Modell, who was responsible for stealing away the city’s franchise. First of all, he turned them into a shambles of a team. They endured 30 years of purgatory under his reign before he did the unforgivable.

Modell decided to move the Browns from Cleveland to Baltimore. This caused fury in the city, with massive protests outside of the stadium during their last season. The only bright side was that he left the name and team colors behind. To rub salt into their wounds, the Ravens won two Super Bowls while the Browns still haven’t.
