Cowboys early camp spotlight: Jaydon Blue and Phil Mafah pressing for meaningful snaps behind Javonte Williams

The Dallas Cowboys are only a couple of days into training camp, but the early practices are already shaping a specific competition: who can earn the roster spot as the next dependable option behind Javonte Williams at running back. According to Yahoo Sports, Dallas’s internal camp conversations included the challenge of establishing a reliable RB2, and two players have begun to draw attention by running with confidence and showing speed in front of the coaching staff.

Jaydon Blue is one of the names gaining momentum. In the first practice of camp, Yahoo Sports reported that Blue broke off a long run, a reminder of the kind of burst that made him an appealing prospect in the first place. The practical takeaway for Dallas is that a player who can create chunk plays early in camp gives the offense an extra dimension, especially in situations where the team wants explosive runs without having to rely entirely on its established starters.

Phil Mafah is also being noticed in the same early window. Yahoo Sports described Mafah having several highlights during practice, indicating that he has not just been present in the group but actively involved in the moments coaches track most closely at the beginning of camp. For a team evaluating depth, that matters because the roster spot often goes to the player who consistently shows up in repeatable reps, not just one isolated sequence.

The Cowboys’ camp environment adds urgency. Even though cutting players after only two days is not the norm, the early days are still when first impressions can separate players, particularly for jobs that require trust on short notice. In Dallas’s case, the question is not whether there are multiple bodies at running back, but which player can best support Williams’s workload while also giving the offense a clear plan if the starter needs spell snaps or if the offense goes through a slower stretch.

For fans, these early contrasts are best interpreted as a work-in-progress rather than a final answer. Yahoo Sports’s reporting is based on early practice observations, and training camp competitions routinely evolve as the pads come on, the playbook demands increase, and special teams opportunities become more central to the decision-making. Still, the fact that Blue and Mafah are already drawing notice suggests the team could be closer to sorting out its depth than it was heading into camp.

What to watch next is simple and measurable over the coming sessions: whether Blue’s big-play ability translates into consistent carries, whether Mafah’s practice highlights turn into reliable production in team periods, and whether the coaching staff keeps both players prominent as the staff tests different backfield groupings behind Williams. If either player becomes the clearer fit in pass-protection assignments or in late-down situations, the roster conversation could move quickly.

In the broader NFL roster reality, depth at running back is often one of the first areas where teams feel the squeeze, because injuries and workload management can force the next option into regular touches. Dallas’s early emphasis on RB2, paired with Blue and Mafah’s early flashes, puts their camp track record in the spotlight, and it will likely influence who sticks when the team begins trimming its training-camp roster over time.
