Who Should I Start? Alexander Mattison or Blake Corum

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.

The Los Angeles Rams placed rookie running back Blake Corum (forearm) on Injured Reserve on Tuesday and signed veteran running back Royce Freeman from the practice squad to the 53-man active roster in a corresponding move. Corum is out for the rest of the season after fracturing his forearm in the loss to the division-rival Seattle Seahawks on Sunday in the Week 18 regular-season finale. Kyren Williams will continue to work as the Rams' No. 1 RB for the playoffs, with Ronnie Rivers now likely serving in the top backup role with Corum sidelined. The 24-year-old third-round pick out of Michigan had a small role behind Williams all year in his first season in the NFL and finished with only 58 rushing attempts for 207 yards (3.6 yards per carry), adding seven catches for 58 yards. If he's ready to go for the start of the 2025 season, Corum will likely be a top fantasy handcuff for Williams.
