5. Robert and Jim Irsay – Indianapolis Colts
This father and son duo definitely riled up the masses. First of all, Robert moved the Colts in the dead of night from Baltimore to Indianapolis to avoid the city seizing the franchise. In short, this made him a major hate figure in Maryland. To this day, the Ravens won’t display the Colts name when they host Indianapolis.
After the death of his father, Jim became the youngest ever NFL owner. He helped to bring his franchise a Super Bowl, but his overall lack of class has seen him earn the disgust of many fans. When his mistress overdosed in a house bought with Colts’ money, it really set things off.
