Odell Beckham Jr.
Some trades are more shocking than others but this one rocked the NFL. Nobody expected Beckham to join the Cleveland Browns in 2019. This came after the Giants extended the wideout’s contract as they denied that they wanted to trade him. Beckham became a major star in New York but he had his problems (via Sporting News).

The Browns gave New York a first-round pick, a third-round pick, and safety Jabrill Peppers for their troubles. In the end, this was one of the worst trades of the past decade because Beckham spent most of his time on the bench injured. He also had a tense relationship with QB Baker Mayfield. Beckham abruptly quit the Browns for the Rams and immediately picked up a Super Bowl ring.
