The Dallas Cowboys RB depth chart is topped by DeMarco Murray and Lance Dunbar, which leaves Joseph Randle and Ryan Williams battling it out for what likely will be one roster spot.

"[Randle] must play well in the preseason to fend off Ryan Williams because the Cowboys probably aren't keeping four running backs," noted ESPN Cowboys reporter Jean-Jacques Taylor.

Does Randle or Williams have an edge in the competition?
