Trent Richardson
Mostly everybody thought that Richardson was going to become an NFL superstar. However, he went down as one of the worst busts in NFL history. The Browns drafted him in 2012 and they made him the third overall pick. But they traded him two games into his sophomore year in one of the biggest deals of the past decade (via Fansided).

The Colts gave Cleveland a first-round pick in exchange for the running back. Unfortunately, this was a terrible decision because he didn’t do anything productive for them. Richardson ran for a combined total of 316 yards in two seasons before he flamed out of the NFL. He had a brief foray into Canadian football but never did anything special.
