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.

Dallas Cowboys running back Javonte Williams good a lot of work with the first-team offense at training camp practice on Tuesday, according to Nick Harris of the Fort Worth Star-Telegram. Williams signed a one-year deal with Dallas in free agency this offseason and is expected to share backfield duties in 2025 with Miles Sanders. The Cowboys also drafted Jaydon Blue and Phil Mafah, but they probably have a ways to go before threatening either Williams or Sanders for serious playing time in 2025. Williams, who was a second-round pick by the Denver Broncos in 2021 out of North Carolina, impressed with 903 rushing yards in his first season, but he hasn't been the same tackle-breaking RB since tearing his ACL in his sophomore season in 2022. He should be the favorite to lead Dallas' backfield in touches, but for fantasy purposes, he's merely an RB3/flex target.
