Who Should I Start? Alexander Mattison or Javonte Williams

Thursday, March 13, 9:35 PM

Former Las Vegas Raiders running back Alexander Mattison is signing an undisclosed deal on Thursday with the Miami Dolphins, sources told FOX Sports' Jordan Schultz. Earlier in the day, former Dolphins RB Raheem Mostert signed with the Raiders in free agency. The 26-year-old Mattison joined the Raiders in 2024 after spending his first five years in the NFL with the Minnesota Vikings. He eventually took over the lead-back role from a disappointing Zamir White and carried the ball 132 times for 420 yards and four touchdowns (a career-low 3.2 yards per tote) in 14 games (seven starts), adding a career-high 36 catches for 294 yards and another score. Mattison's move to Miami is a big downgrade, as he'll merely be competing for a change-of-pace role with Jaylen Wright behind unquestioned starter De'Von Achane. He'll be avoidable in most fantasy drafts this fall.

The Dallas Cowboys have signed free-agent running back Javonte Williams on Monday. The two sides have agreed to a one-year, $3 million contract that carries a maximum value of $3.5 million through incentives. This is a low-risk move by the Cowboys to address the lack of depth in their backfield. The assumption is that Williams will serve as the backup to Rico Dowdle to begin the season. However, the Cowboys could still add more backs through free agency or the upcoming NFL draft. Williams has been unable to live up to the hype of his rookie season where he rushed for 903 yards in 2021. The 24-year-old was stuck in a backfield committee last season with the Denver Broncos. There's a good chance Williams ends up in a committee type of approach in Dallas, so this move shouldn't give fantasy managers too much confidence in a bounce back campaign from Williams.
