17. Carson Wentz
Philadelphia Eagles fans are infamously some of the least forgiving in the NFL. They hate Wentz more than anyone else in the league because he let them down badly. It appeared as though he was the next big thing and their new generation’s leader. But then he had a stark decline and took 50 sacks in 2020.

They wanted him out of the organization but he came back to haunt them. The Colts promised the Eagles a first-round pick if Wentz reached a 75 percent snap threshold. However, he suffered injuries and then fell ill after violating NFL health regulations. No wonder they can’t forgive him (via The Guardian).
