Who Should I Start? Bam Knight or Sione Vaki

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.

Detroit Lions running back Sione Vaki rushed for 30 yards on five carries in his 2025 preseason debut against the Miami Dolphins on Saturday. Vaki has been dealing with a lingering hamstring injury throughout training camp, but he returned to practice in full earlier this week. The second-year back is "showing good vision and wiggle," according to Colton Pouncy of The Athletic. A fourth-round pick out of Utah in 2024, Vaki is competing with veteran Craig Reynolds for the RB3 job in Detroit behind Jahmyr Gibbs and David Montgomery. Vaki is still new to the running back position after playing mostly as a safety in college, so his development could take longer than the average young player. With Gibbs and Montgomery ahead of him on the depth chart, Vaki is highly unlikely to be fantasy-relevant in 2025.
