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.

Los Angeles Rams running back Blake Corum (forearm) has been taking part in voluntary organized team activities this offseason after fracturing his forearm in the Week 18 regular-season finale. It's a good sign that Corum will be ready for the start of his second NFL season as the primary backup to Kyren Williams. After being taken in the third round (83rd overall) last year out of Michigan, the 24-year-old had a minimal role behind the workhorse Williams, carrying the ball only 58 times for 207 yards while adding seven catches on eight targets for 58 yards. He did not find the end zone at all. Heading into Year 2, Corum is competing with rookie fourth-rounder Jarquez Hunter for backup duties in L.A. Corum's quiet rookie season wasn't what fantasy managers in dynasty/keeper leagues wanted to see, and it might take an injury to Williams for him to see a bigger role in his sophomore season.
