Josh Gordon
The Gordon hype train was in full effect in 2013 after an outstanding season. He earned an All-Pro selection after he led the league in receiving yards. This seemed to vindicate the Browns’ decision to draft him. Fantasy Football fans licked their lips the following year (via The Cauldron).

But Gordon’s substance abuse problems changed the narrative. He barely played for the rest of his career because of suspensions. Finally, Cleveland threw him away like yesterday’s garbage. In 2018, he started 18 games with New England as the Pats won the Super Bowl. But there’s no doubt that he seriously underachieved.
