15. Michael Irvin (1999)
Philadelphia sports fans are some of the most notorious in the sports world. They have a reputation for being extremely tough on their own players. Then, they can be horribly threatening to opposing teams and players. Remember the time they threw snowballs at Santa? However, they sunk to a new low in 1999 when the Eagles hosted the Dallas Cowboys. In short, it was their most shameful display.

Irvin was a very effective receiver and enjoyed an 11-season career in the NFL. The Cowboys star was a three-time Super Bowl winner and made the Pro Bowl five times. His achievements didn’t endear him to the Eagles’ support because they cheered when medics stretchered him off. It was a disgusting reaction from the crowd. This got worse because the injury was career-threatening and he retired as the risk to his health was too great.
