Who Should I Start? Alexander Mattison or J.K. Dobbins

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.

ESPN's Jeff Legwold writes that the Denver Broncos figure to give new running back J.K. Dobbins a long look in the third-down role ahead of Week 1 of the 2025 regular season. Dobbins has dealt with multiple injuries since being drafted in 2020, mainly knee and Achilles injuries, but he had career-highs in rushing yards (905), catches (32) and receiving yards (153) last year with the Los Angeles Chargers and tied his career best with nine rushing touchdowns. And that was with him missing four games in 2024 with an MCL sprain. Javonte Williams led the Broncos in carries (139) and rushing yards (513) last year, but he's now in Dallas. Second-round rookie RB RJ Harvey is the favorite for lead-back duties in 2025, but Dobbins (if healthy) could be a nice RB3/flex option for fantasy managers in PPR leagues if he captures the full-time third-down role.
