Le’Veon Bell
These days, Bell admits that his Pittsburgh holdout was the biggest mistake of his career. The running back was phenomenal in 2016 as he surged for 1,884 yards in 12 games. Everybody assumed that he would sign the franchise tag in 2018 after he failed to agree on an extension (via Fox News).

Instead, he sat out for the entire season as he refused to change his position. But the Steelers didn’t blink so he sat on the sidelines as he missed the full year. Bell joined the Jets in 2019 but this was a disaster and he quit the franchise in disgust. Finally, he fell out of the NFL after three games for Kansas City.
