Which of 3 Cowboys running backs makes the most sense as the backup?

Last season was a disappointing campaign for both Dallas Cowboys rookie running backs, Jaydon Blue and Phil Mafah. Both dealt with injuries as Blue missed time due to a right ankle and heel, while Mafah landed on IR early with a shoulder injury, only playing in the season finale. With neither running back able to see the field consistently, practice squad darling Malik Davis inserted himself into the running back discussion.

Now as prep work for the 2026 season is underway, both second-year pros are healthy and looking to incorporate their skill sets into a rejuvenated Cowboys rushing attack. Which one has the best chance to see more time on the field in relief of lead back Javonte Williams? Many believe Blue's speed has the best chance to add firepower to the offense, as he's a threat in both the running and passing game.

Blue does provide more explosiveness, something the Cowboys have been missing out the backfield. Davis flashed when called upon last season, in both catching and running the football. Unfortunately, his season ended after he suffered an eye and calf injury in Week 17.

Both have the talent, but it's actually Mafah who will have a greater impact. This has more to do with Williams rather than each player's individual skill set. Mafah has the upper hand for two reasons: if Williams were to go down with an injury during the season, the running back best suited to fill in for him would be the bigger and more physical Mafah.
