8. Philadelphia Eagles – Trading Away LeSean McCoy
With the Philadelphia Eagles securing their first Super Bowl win in 2017, it seemingly erased all the disaster that took place as part of the Chip Kelly era just a few years earlier. When Kelly arrived in town, he seemingly clashed with running back LeSean McCoy right from the get-go, as the latter appeared to not fully buy into what the former was selling.
Despite them publicly saying they got along, Kelly traded away McCoy, one of the most beloved members of the franchise, for linebacker Kiko Alonso. In just his second game with the Eagles, Alonso tore his ACL.
