2Duke Thomas, Cornerback

Entire Cowboys secondary is formed from a young core of players, and Thomas was supposed to be a part of it. He was one of the best at his position during the preseason, but he was struck with a season-ending foot injury. Duke will have another chance to fight for his job during this offseason. Although many fans probably forgot about him, we are sure he will have a spot on Cowboys 2018 roster.
