Who Should I Start? Alexander Mattison or Najee Harris

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.

According to Los Angeles Chargers reporter Daniel Popper of the Athletic, the team is likely to target a running back in April's 2025 NFL Draft. "The Chargers will be adding an explosive player to this group in the draft to complement Harris, Popper wrote." Perhaps as early as the 22nd pick in the first round." Harris signed a one-year, $5.25 million deal to join Justin Herbert's offense during the first week of free agency, but the depth chart behind him consisting of Kimani Vidal and Hassan Haskins leaves a lot to be desired. The 2025 NFL Draft class is loaded at the running back spot, and North Carolina's Omarion Hampton or Ohio State's TreVeyon Henderson could fit what L.A. is looking for. While Harris would have immense upside in the Chargers' offense in a workhorse role, he could be related to early-down work depending on if L.A. pulls the trigger on a ball carrier on Day 1 or Day 2. Harris has missed just one game in his NFL career and has rushed for at least 1,000 yards in each of his first four seasons, but his contract value and lack of explosive play-making signals he could be at risk of falling into a committee-back role.
