Dallas preseason kickoff vs. the Rams highlights a markedly unsettled Cowboys backfield, with Miles Sanders sidelined early and Javonte Williams and a rotating group behind him. Deuce Vaughn, Phil Mafah, Hunter Luepke, and Malik Davis are all slated for reps in a plan Schottenheimer calls ‘vanilla’ but with room for creative packages. The backfield’s health will shape early-season usage, and the coaching staff envisions a three-game arc totaling about 40 snaps, including a 15-snap stint with the Rams. For fantasy, this sets up Vaughn as a high-upside late-round flyer if Sanderson’s absence persists and Mafah/Davis carve carved roles in the three-game slate.
