12. Martellus Bennett, Green Bay Packers (2017):
An enigmatic personality, Bennett was a solid if not spectacular performer at the tight end position for most of his 10 seasons in the league. But when Green Bay signed him to a three-year, $21 million contract before the 2017 season, things got a bit weird.
Bennett reportedly failed to admit he had a torn rotator cuff and labrum in his shoulder and was released by the team. He claimed that the team had pressured to play with the serious injury. Somehow he was signed by the New England Patriots and played on November 12 of that year. He was eventually placed on injured reserve due to the injury on November 27. He was released on March 7, 2018, and retired from the NFL 16 days later. A solid career, but a strange ending that made him a massive free agent disappointment in Green Bay.
