Who Should I Start? Alexander Mattison or Kyren 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.

Los Angeles Rams general manager Les Snead indicated that the team might be open to working out a long-term contract extension with running back Kyren Williams this offseason after he had another strong year in 2024. Williams accounted for almost 81% of the Rams' rushing attempts out of the backfield this year and ran the ball 316 times for a career-high 1,299 yards and a career-high 14 rushing touchdowns while adding a career-high 34 catches (40 targets) for another 182 yards and two scores through the air in 16 regular-season games. He'll be heading into the final year of his rookie deal in 2025, which makes him eligible for a contract extension this offseason. The 24-year-old has gone for 1,000 rushing yards in each of the last two years and is the first Rams RB since Todd Gurley to score 14 rushing TDs in a single season. Williams will be a strong RB1 choice for fantasy managers in 2025.
