Who Should I Start? Sione Vaki or Terrell Jennings

Sunday, August 17, 10:00 AM

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.

New England Patriots running back Terrell Jennings rushed for 38 yards on six carries during Thursday's preseason opener against the Carolina Panthers. He also contributed in the passing game, hauling in both of his targets for a total of 11 yards. Jennings is a 23-year-old undrafted rookie out of Florida A&M. Despite his strong pro debut on Thursday, he faces an uphill battle to make the roster behind the likes of Rhamondre Stevenson, Antonio Gibson, Kevin Harris, and JaMycal Hasty. He can be avoided in all fantasy formats.
