Who Should I Start? Alexander Mattison or DJ Giddens

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.

Indianapolis Colts rookie running back DJ Giddens will likely have the opportunity to win the RB2 job, and he could earn a weekly role on offense if he proves capable in the pass-blocking and pass-catching game, according to team reporter Jake Arthur. "Giddens may carve out some sort of role regardless of what's going on ahead of him with Jonathan Taylor and/or Khalil Herbert," Arthur wrote. "The Colts really like Giddens." The Kansas State product was the No. 151 overall pick (fifth-round) in the 2025 NFL Draft after posting 2,469 rushing yards, 581 receiving yards, and 21 total touchdowns over his final two collegiate seasons. He'll be competing with Herbert and Tyler Goodson to earn a spot behind Jonathan Taylor. For now, he's a late-round handcuff stash in deeper fantasy football leagues, but he's worth monitoring early in his first professional campaign.
