Jon Gruden
Nobody will deny that Gruden deserved to lose his job after he resigned in 2021. However, it’s also true that he was the fall guy for one of the NFL’s most sordid scandals. Gruden sent dozens of emails to Washington Team President Bruce Allen. They exchanged racist, sexist, and sordid opinions about players, coaches, and executives.

But Gruden took the hit so that the media would focus on him instead of the NFL’s culture. The league investigated 650,000 emails so it’s safe to assume there was more going on beyond the scenes. This allowed them to suppress the rest of the emails and sweep the scandal under the rug. Gruden became one of the biggest scapegoats ever (via The Daily Beast).
