Cowboys coach Brian Schottenheimer said RB Jaydon Blue and RB Phil Mafah “are going to get a bunch of work” in the preseason.

Per Schottenheimer, Blue and Mafah “are in a tight battle for the backup running back spot.” Blue has received positive reports for some time now. His speed and receiving ability make him an ideal complement to starting RB Javonte Williams, who “probably won’t get a whole lot of run” in the preseason. If Blue can secure the role, he could warrant FLEX treatment on a weekly basis. Mafah (6'/234) is a burly rusher. Were he to win the RB2 job, he may be ill-suited to playing on passing downs, which could benefit Williams. We’ll see how things shake out in the preseason. Stay tuned.
