Who Should I Start? Alexander Mattison or Trey Sermon

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 running back Trey Sermon carried the ball eight times for 36 yards in the team's 16-10 win over the Miami Dolphins. Sermon also caught his only target for another 13 yards through the air. Sermon took a backseat to running back Tyler Goodson in Sunday's matchup, being out-touched 14-to-nine, marking the first time Goodson had the higher opportunity share since the two overtook the backfield in Jonathan Taylor's (ankle) absence. Sermon had some issues with efficiency in the previous week but improved on that, averaging 4.5 yards per carry on Sunday. Sermon's fantasy value does take quite a hit with Goodson's expanded role, and the two may both be off the radar in Week 8 if Taylor were to return. If Taylor sits out again in Week 8 against the Houston Texans, Sermon can be viewed as a RB3/4 option.
