Laphonso Ellis isn't the most known guy on this list, but his game and potential may rival some of the most famous players in the league. He was drafted No. 5 overall out of Notre Dame by the Nuggets and started off his NBA career strong with two solid seasons that made experts feel like he would be a premier power forward in the game going into his third season.

Just like the stories of many others on this list though, a stress fracture to his right knee kept him off the court for nearly his entire third season. That injury paired with more to his other knee and a sports hernia plagued Ellis for the rest of his career, never fully allowing him to live up to the hype. Remember he actually did this.
