Gregory had injured his knee in his last collegiate game, and the knee gave out during training camp. Following scathing criticism from the press for wasting a pick on damaged goods, the Broncos traded him to the Saints for Shawn Knight before the season. He is now regarded as one of the biggest draft busts in Broncos' history (if not the biggest). After the Gregory incident the Broncos began meeting with potential draft picks prior to the draft, a practice they had not previously engaged in.
Gregory blew out his knee in this third game with the Saints, and never played in the NFL again. After a series of failed business ventures drained his life savings, he took a job as a construction worker, only to have that end due to a ruptured disc in his back. Gregory placed 8th in Deadspin's "The 100 Worst NFL Players of All Time".
