Who Should I Start? Bam Knight or Phil Mafah

Arizona Cardinals running back Bam Knight saved his best game for last in the preseason victory over the Las Vegas Raiders on Saturday. The 24-year-old led all rushers in yards and touchdowns after he registered 83 yards on five carries and a big 67-yard touchdown run. Knight was able to find a hole right up the middle and break away from the Raiders' defense at the end of the third quarter. There hasn't been any official word on the depth chart yet, but Knight could have put plenty of pressure on Emari Demercado and DeeJay Dallas for the final RB spot.

Dallas Cowboys rookie running back Phil Mafah (shoulder) has been placed on injured reserve, sidelining him for at least the first four games of the regular season with a shoulder injury suffered in the preseason finale. The seventh-round pick out of Clemson showed flashes in the preseason with 15 carries for 59 yards and a touchdown, good for a solid 3.9 yards per carry. Standing six-foot and weighing 234 pounds, Mafah's big-bodied, between-the-tackles style was impressive in his final college season, rushing for 1,115 yards and eight touchdowns. His placement on IR is a setback, but with the Cowboys' current running back situation, a potential revolving door of Javonte Williams, Miles Sanders, and Jaydon Blue, Mafah remains a potential contributor later in the season. He is worth a roster spot in deeper dynasty leagues. Still, his fantasy value will stay uncertain until he returns to full health and the backfield situation becomes clearer throughout the season.
