Cowboys rookie running back Jaydon Blue heard the pre-training camp criticism of his work ethic and turned it into motivation. This week, he's taken reps with Dak Prescott and the first-team offense.

Jaydon Blue is using the 'fake story' claiming Dallas Cowboys coaches were concerned about his work ethic as motivation for the upcoming NFL season.

Blue is at least giving first-year Cowboys coach Brian Schottenheimer an unexpected dilemma with his two-deep on offense ahead of the regular season. Blue's competing with Javonte Williams, Miles Sanders and Deuce Vaughn for essentially one of two roles within the Dallas scheme — lead back or a dependable second weapon.
