11. Ezekiel Elliott
On one hand, Elliott didn’t do anything wrong when he began his contract holdout. But context is an important thing considering what happened the previous season. The NFL hit him with a six-game suspension after domestic assault allegations (via NFL.com).
Elliott didn’t feel any sentiment toward the Cowboys as he demanded that they pay him his full value. Furthermore, he was only in the fourth year of his five-year rookie contract. He threatened to leave his team hanging ahead of the 2019 season.
